Question

A boy walks to his school with a constant speed of 4 k.m/h and reaches there in 30 min.s . Find the distance of the school from his house.

Answer 1

According to the question,

Constant Speed of the boy = 4 km/h

Time taken by the boy = 30 minutes = 0.5 hour

Applying the formula, distance = speed × time = ( 4 km/hr × 0.5 ) km = 2 km.

Thus, distance of school from his house is 2 km.

Answer 2

given

speed= 4km/h
time=30 minutes=30×1/2h
distance=?
distance = speed×time
=4 km/h ×1\2 hour
distance=2 km
