A boy walks a distance 30 m in 1 minute and another 30 min in 1.5 minutes. Describe the type of motion of the boy and find his average speed in m\s.

Answer:

0.4ms-1 is the answer.

Step-by-step explanation:

As the speed does not remain constant throughout the journey the motion is non-uniform.

Total distance travelled in going and coming back,

d=30m+30m=60m

Total time taken in going and coming back

t=1min+1.5min=2.5min=2.5×60s=150s

Average speed = Total time of travel

Total distance travelled = 150s60m

=0.4ms −1
