Question

An object covers a distance of 30m in 1.5 minutes. Find the speed of the object.

Answer 1

distance = 30m
time = 1.5 min = 1.5 *60 = 90 secs
speed = distance / time
= 30 / 90
= 1/3 m/s

Answer 2

Distance = 30m
Time = 1.5min = 1.5 × 60sec = 90sec

Speed = Distance/Time
= 30m/90sec
= 0.33m/s
