Question :-

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.

____________________

Solution :-

Given Information :-

• Speed of the boy ( V ) ➢ 4 km/h
• Time taken to reach school from house ( T ) ➢ 30 min = $\sf {\frac{30}{60} \: hour(s) }$
• Speed of the boy is constant

To Find :-

• The distance of the school from his house ( D )

Formula Used :-

• $\boxed{ \bf D = V \times T}$

Calculation :-

• We'll simply substitute the given values in the formula, and then get our answer.

⇒ D = V × T

Substituting the values, We get,

⇒ D = $\sf (4 \times \frac{30}{60} )$ km

Calculating further, We get,

• ⇒ D = $\bf{ 2\:km}$

Final Answer :-

• The distance of the school from his house was $\bf{ 2 \: km}$
