2. A car travelled on a B class road for 20 minutes at an average speed of 57 km/h. It then travelled a distance of 55 km in 30 minutes on an expressway, find: a) the distance the car travelled on the B class road b) the average speed, in km/h, of the car when it travelled on the expressway.
Penjelasan dengan langkah-langkah:
a. t1= 20 mnt
v1= 57 km/h
v=s/t
57×20=s
S1=114 km
b. V=s/t
v=55/0.5
=27.5 km/h
good luck

4. 1. Kate travelled for the first 1 ½ hours at an average speed of 64 km/h and the next 2 ½ hours at 72 km/h. Find the average speed for the whole journey!..
[tex] \frac{(1,5 \times 64) + (2,5 \times 72)}{1,5 + 2,5} \\ \\ \frac{96 + 180}{4} = \frac{276}{4} = 69 \frac{km}{h} [/tex]
5. In a triathlon, Ari cycles 50 km in 1.75 hours, swims a distance of 1.2 km at an average speed of 2.5 km/h, and runs at an average speed of 9km/h for 10/9 hours. Find his average speed for the entire competition.
Answer:
18.31 km/hrExplanation with steps:
Average speed = Total distance / total timeCycling distance = 50 km, cycling time = 1.75 hr
Swimming distance = 1.2 km, swimming time = 1.2/2.5 = 0.48 hr
Running distance = 9 x (10/9) = 10 km, running time = 10/9 hr
Therefore
Average speed = Total distance / total timeAverage speed = (50 + 1.2 + 10) / (1.75 + 0.48 + (10/9))
Average speed = 61.2 / (3007/900)
Average speed = (61.2 x 900) / 3,007
Average speed = (61.2 x 900) / 3,007
Average speed = 55,080 / 3,007
Average speed = 18 954/3,007
Average speed = 18.31 km/hr

9. The distance between Town A and Town B is about 600 km. A Train leaves Town A at 10 a.m. for Town B. At what time would it reach Town B if it travelled at an average speed of 60 km/h?
Time= Distance ÷ Speed
= 600 ÷ 60
= 10 hours
10 a.m + 10 hours= 8 p.m

10. An aeroplane travelled at a speed of 808 km/h. Calculate the distance it covered in 7 h 15 min
Jawaban:
5.858km
Penjelasan dengan langkah-langkah:
Soal Ke bahasa Indonesia:
Sebuah pesawat terbang dengan kecepatan 808 km / jam. Hitung jarak yang ditempuh dalam 7 jam 15 menit
BHS. Inggris
Distance formula: Speed × Time
= 808 × 7 hours 15 minutes
=808 × 7,25 =5.858 km
Then the distance = 5.858 km
BHS. Indonesia
Rumus Jarak: Kecepatan×Waktu
=808×7 jam 15 menit
=808× 7,25=5.858 km
Maka Jaraknya=5.858 km
Answer:
if the plane reaches 808 km in 1 hour then, in 7 hours 15 minutes, the plane will cover the distance (808km x 7.25 hours) = 5858km
11. 2. A car travelled 3 hours with the average speed of 80km/h. In order to arrive faster toits destination the car speeded up its average speed become 120km/h for 2 hours.What was the total distance the car travelled?
Jawab:
80 km/h = 80*3 = 240 km
120 km/h = 120*2=240 km
total distance = 240

12. A bird can fly at an average speed of 96 km/h.How many minutes will it take to fly a distance of 8km? (kasih caranya juga)
Jawab:
Penjelasan dengan langkah-langkah:
S = V.t
s = displacement
v = velocity
t = time
diketahui v = 96 km/h dan s = 8 km
t = s/v = 8/96 = 1/12 h
1/12 × 60 = 5 minutes

Materi : Perbandingan dan Skala
Bagian A
Laki - Laki : Perempuan
= 100 : 70
= ( 100 ÷ 10 ) : ( 70 ÷ 10 )
= 10 : 7
Bagian B

17. farhan cycles the first part of 150km journey at an average speed of 35 km/h and walks the remaining distance at an average speed of 5 km/h. if he takes 4,5 hours for his entire journey, find the distance that he cycles
Time 1 (First part)
= 150km : 35km/h
= 4 2/7 h
Time 2 (Remaining distance)
= 4,5 - 4 2/7
= 4 1/2 - 4 2/7
= 4 7/14 - 4 4/14
= 3/14 h
Distance 1 = 150km
Distance 2
= Speed x Time
= 5 km/h x 3/14 h
= 1.07 km
Total Distance
= 150 + 1.07
= 151.07 km
18. A motorist took h to drive from Kembangan to Karawaci at an average speed of 95 km/h. Then he took another h. from Karawaci to Bitung at an average speed of 85 km/h. Find the total distance he travelled. 3 h to drive 5
Jawab:
108 km
Penjelasan dengan langkah-langkah:
1. kembangan to karawaci (kk):
• speed ( v. ) = 95 km/h
• time ( t. ) = 3 / 5 hour
• distance ( S. ) = ?
• S(kk) = v x t
= 95 x ( 3 / 5 )
= 19 x 3
= 57 km
2. karawaci to bitung (kb) :
• speed ( v. ) = 85 km/h
• time ( t. ) = 3 / 5 hour
• distance ( S. ) = ?
• S(kb) = v x t
= 85 x ( 3 / 5 )
= 17 x 3
= 51 km
total distance = distance kembangan to karawaci + distance karawaci to bitung
= Skk + Skb
= 57 + 51
= 108
total distance he travelled is 108 km.
