Questions on Physics
1. A car travels a distance of 100 metres in 20 seconds. What is the speed of the car?
d = 100m
t =20s
v = d/t
v = 100/20
v = 5m/s
2. A bike travels at a speed of 20 m/s for 20 seconds. How far does the bike travel in this time?
v = 20m/s
t = 20
d= v x t
d =20 x 20
d = 400m
3. A car travels at 30 m/s for 2 minutes. How far has it travelled in this time?
v = 30m/s
t = 120s
d = v x t
d = 30 x 120
d =3600m
4. A car travels at 30 km/hour. How far, in metres, will the car cover in 90 seconds?
v = 8.3m/s
t = 90s
d = v x t
d = 8.3 x 90
d = 750m
