Answer it steps by steps​

Answer 1

Answer:

since the boy has gone to shop and then again returned to home. Hence, he has totally travelled distance of 4km.

Here, time is 1hr which is equal to 3600seconds

SPEED = DISTANCE /TIME

SPEED = 4KM/1HR

SPEED = 4000M/3600

SPEED = 10/9

SPEED = 1.11 M/S
