The motion of he boy is non-uniform as he is covering equal distances in unequal amount of time.
Total distance covered = 30+30=60m
Total time taken= 1+1.5=2.5 mins = 150 seconds
Therefore, avg speed = total d/total t
= 60/150 = 0.4 m/s
Total distance covered = 30+30=60m
Total time taken= 1+1.5=2.5 mins = 150 seconds
Therefore, avg speed = total d/total t
= 60/150 = 0.4 m/s
