1. John drove for 3 hours at a rate of 50 miles per hour and for 2 hours at 60 miles per hour. What was his average speed for the whole journey?

Jawab:

Penjelasan dengan langkah-langkah:

(50x3+60x2)/(3+2)

150+120/5

270/5

54

So his avarage speed for the whole journey was 54 miles/hour

Penjelasan dengan langkah-langkah:

average speed = (3x50)+(2x60) / (3+2)

= 270/5 = 54milesperhour

2. An airplane travels 200 miles due west, and then 150 miles 608 north of west. determine the resultant displacement.

Consider X-axis as West - East.

Consider Y-axis as North - South.

The plane starts from O (0, 0).

First it goes 200 miles due West to A (- 200, 0).

Then it goes to B, say (p, q).

So, AB is 150 miles 60° North of West.

So, p - (- 200) = - 150 * cos 60°

Or, (p + 200) = - 150 * 1 / 2 = - 75

Or, p = (- 200 - 75)

Or, p = - 275

And, q - 0 = - 150 * sin 60°

Or, q = - 150 * (√3) / 2 = - 75√3

Or, q = - 75√3

Thus, final location of the aircraft = B (- 275, - 75√3).

Therefore, magnitude of resultant displacement = |√[{(- 275)^2} + {(- 75√3)^2}]| miles = √(75625 + 16875) miles = √92500 miles ≈ 304.138 miles.

And, direction of resultant displacement = arc tan {(- 75√3) / (- 275)} = arc tan {(3√3) / 11} = 25.284° North of West.

i copied this answer from a forum in quora, dont get me wrong. but the end results varies

3. bantu jawab yaTwo cars 720 kilometers apart travel toward each other. One car travels 70 kilometers per hour while the other car travelsat the rate of 50 kilometers per hour. In how many hours will they meet?​

Jawab:

Bahasa Indonesia =  

Dua mobil berjarak 720 kilometer terpisah satu sama lain. Satu mobil melaju 70 kilometer per jam sedangkan mobil yang lain melaju dengan kecepatan 50 kilometer per jam. Dalam berapa jam mereka akan bertemu?

Penjelasan dengan langkah-langkah:

Jarak = 720 kmKecepatan = 70km/jam + 50km/jam = 120km/jamWaktu = J/K = 720/120 X 60 =360 MENIT : 60 =  6 jam

Bahasa Inggris =

Distance = 720 km Speed ​​= 70km / hour + 50km / hour = 120km / hour Time = J / K = 720/120 X 60 = 360 MINUTES : 60= 6 hours

semoga membantu dan maaf jika jawaban saya salah

4. The area of a circle is decreasing at the rate of 10 cm/s. Find the rate of changes of the radius for circle when the area is 5 m^2.​

Jawaban:

Tidak semua bahan dapat digunakan sebagai wadah penyajian atau kemasan pangan olahan. Ada beberapa kriteria tertentu wadah penyajian yang harus diperhatikan dalam pemilihan wadah penyajian atau kemasan, yaitu:

1. Bahan kemasan atau wadah penyajian tidak berbau sehingga tidak memengaruhi atau mengubah rasa dari produk pangan olahan.

2. Kemasan atau wadah penyajian memiliki kekuatan sebagai tempat produk pangan olahan.

3. Bahan kemasan atau wadah penyajian mudah didapat.

4. Bahan kemasan atau wadah penyajian aman bagi kesehatan dan bersih.

Adapun tempat penyajian atau pengemasan makanan dan minuman yang biasa digunakan masyarakat terbuat dari kertas, plastik, ataupun styrofoam dan wadah penyajian umumnya berbahan kaca.

Selain memberikan manfaat sebagai wadah penyajian dan kemasan, juga berhubungan dengan cara menampilkan produk atau hasil olahan tangan dalam bentuk menarik. Bentuk yang menarik dapat pelanggan dapat memancing daya tarik pelanggan untuk membeli produk olahan pangan tersebut ataupun menambah selera pelanggan.

Banyak restoran yang memberikan tampilan unik, eksotis, dan berkarakter pada kemasan atau penyajian produknya. Seperti gerabah ataupun batok kelapa yang bisa menjadi gelas cantik. Ada juga yang memodifikasikan bahan seperti plastik dan kertas menjadi kemasan produk olahan pangan. Oleh karena itu saat ini bisnis kemasan dan wadah penyajian memiliki prospek menguntungkan. Kreatifitas kita sangat dibutuhkan untuk dapat menciptakan wadah penyajian maupun kemasan.

5. A bird leaves its nest and travels 18 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after x hours. a. What is the distance of the entire trip? ____miles b. How long does the entire trip take? ____ hours ____ minutes and ____ seconds

Jawaban:

a. 30 miles

b. 1 hour 40 minutes

Penjelasan dengan langkah-langkah:

dari soal diatas, satu satunya yang sama afalh total jarak tempuhnya. dari kejadian awal

s = v x t

s = 18X

dari kejadian kedua

s = 15X + 5

substitusi nilai s

15X + 5 = 18X

3X = 5

X = 1 hour 40 minutes

s = 30 miles

6. Water flows from a tap at a rate of 13 liters every 5 minutes. At this rate, how long will it take for the tap to fill 117 liters?

Jawaban:

45 minutes

Penjelasan dengan langkah-langkah:

13/117 = 5/x

13x = 585

x = 45

7. The time needed to travel a certain distance varies inversely with the rate of speed. If it takes 8 hours to travel a certain distance at 36 miles per hour, how long will it take to travel the same distance at 60 miles per hour?

Fotoooooooooo!!!!!!!!!

9. a train running between two stations 50km apart arrives on time if it travels at an average speed of 60 km/h. How late will it be if it travels at an average speed of 50 km/h?

On time :
s=50 Km
v=60km/h
t = s : v
= 50Km : 60Km/h
= 5/6 h

Late :
s=50Km
v=50Km/h
t = s : v
= 50Km : 50Km/h
= 1h

1h - 5/6h = 1/6h
1/6h = 1/6 x 60min = 10min

At an average speed of 50Km/h, the train will be 10 minutes late.

10. The distance between town p and town q is 216 km. At 11. 50 a. M. , a van travels from town p to town q at a constant speed of 48 km/h. At the same time, a car travels from town q to town p along the same route at a constant speed of 60 km/h. At what time will the two vehicles meet?.

[tex] \frac{distance}{speed1 + speed2} \\ \\ \frac{216 \: km}{48 \frac{km}{h} + 60 \frac{km}{h} } \\ \\ \frac{216}{ \frac{108}{h} } = 2 \: h \\ \\ 11.50 + 02.00 = 13.50 \\ 13.50 - 12.00 = 01.50 \: pm[/tex]

13. A typical jetliner lands at a speed of 160 mi/h and decelerates at the rate of (10 mi/h)/s. If the plane travels at a constant speed of 160 mi/h for 1.0 s after landing before applying the brakes, what is the total displacement of the aircraft between touchdown on the runway and coming to rest? [644 m]

Jawaban:

643,34 Meters

Penjelasan:

[tex]v_t[/tex] = 0 (Rest)

[tex]v_0[/tex] = 160 mi/h = 71.5 m/s

a = - 10 mi/h = -4.47 m/s (Braking action)

A. Coasting distance

[tex]s = \frac{v}{t} \\s = \frac{71,5}{1}\\s = 71,5 m[/tex]

B. Braking distance

[tex]v_t^2 - v_0^2 = 2a.s\\0 - (71.5)^2 = 2.-4.47s\\0 - 5112.25 = 8.94s\\s = \frac {5112.25}{8.94}\\s = 571,84 m\\\\[/tex]

∑s = 571.84 + 71.5 = 643,34 Meters

15. If a trip of 270 miles required 12 gallons of fuel, how many gallons are required for a trip of 400 miles

Jawaban:

400 miles/270 miles x 12 gallons

= 4.800/270

= 17 210/270

= 17 21/27

= 17 7/9 gallons
