3. 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. 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

*from cm to m down 2 stairs
6. a car travels at a speed of 55 km/h. find the distance travelled by the car in 12 minutes 30 seconds, giving your answers in metres.
Jawaban:
distance = speed * time
car speed is = 55kmph convert in m/sec
55×5/18≈15.27 m/sec (x×1000/3600=5/18)
=15.27×12.30
=188km the distance travelled by car

18. Samad travelled a distance of 17 km. He cycles part of the journey at 16 km/h and runs the remaining journey at 6 km/h. His total time taken is 2 hours. Find his cycling distance.
Jawab:
a) First distance is 17 km
b) First speed is at 16 km/h
c) Second speed is at 6 km/h (remaining journey)
First 1 hour with 16 km/h is:
= 16 km/h x 1
= 16 km
Remain of 1 hour is 6 km/h:
= 6 km/h x 1
= 6 km
Total distance is:
= 17 km + 16 km + 6 km
= 33 km + 6 km
= 39 km
