Question

1.
A boy walks to his school with a constant speed of 4 km/h and reaches there in
30 minutes. Find the distance of the school from his house.​

Answer 1

Explanation:

Speed = 4 km/h , time = 30 min = 30 /60 h = 0.5

h , we know that :

Distance = Speed × Time

Distance = 4 km/h × 0.5 = 2 km ANS.

Answer 2

Given,

Distance =4km/h

Time=30 minutes

$= \frac{1}{2} \: hr \: (since \: 60 \: mins = 1hr)$

$Distance = Speed \times Time$

$= > 4 \times \frac{1}{2}$

$= > 2 \: km$

Therefore, the distance of the school from his house is 2 km.
