Lesson Summary

A lorry was travelling at a speed of 54 km/h. What was its speed in meters per second?

A.18
B.15
C.12
D.20



Text Answer


Speed of lorry = 54 km/h
For every one hour the lorry travelled 54 km
Distance (D) = 54 km = 54 x 1 000 = 54 000 metres
Time (T) = 1 hour = 60 x 60 = 3 600 seconds.
Now speed (S) =DT=540003600=15
Hence speed = 15 metres per second.

The correct answer is B (15)
