A car is moving along a straight road at a steady speed. It travels 150 m in 5 seconds:

a) What is its average speed?

b) How far does it travel in 1 second?

c) How far does it travel in 6 seconds?

d) How long does it take to travel 240 m?

a) Average speed = total distance travelled/total time taken = 150/5 = 30 m/s

b) Time = 1 s

Distance = (average speed)(time) = 30 m/s

c) Time = 6 s

Distance = (average speed)(time) = 180m/s

d) Distance = 240m

Time = Distance/average speed = 240/30 = 8s
