Question

a race horse runs straight towards north and covers 540m in one minute .Calculate
1.displacement
2.its velocity in m/s and km/h

Answer 1

Displacement is 540 m
velocity in m/s = 540 ÷ 60 m/s[ since 1min = 60 sec]
= 9m/s

velocity in km/h = 540 × 60 ÷ 1000 km/h
= 32.4 km/h

Answer 2

Displacement is 540 m/s

Velocity in m/s =540÷60 m/s

= 9m/s

Velocity in km/h= 540×60÷1000km/h

=32.4km/h
