Question

a boy walks to his school with a constant speed of 4 km per hour and reaches there in 30 minutes . Find the distance of the school from his house .

Answer 1

Speed of the boy=4km/h

Time taken by the boyvto reach School from his house=30 minutes =
$\frac{30}{60} h = \frac{1}{2}h$

Distance of the school from his house=Speed×Time
=4km/h×$\frac{1}{2} h$
=$2 \: km$

Answer 2

${\purple{\underline{\underline{\bf{\pink{Solution:-}}}}}}$

$\mathfrak{\underline{AnswEr:-}}$

• The distance of the school from his house = 2 km

$\mathfrak{\underline{Given:-}}$

• A boy walks to his school with a constant speed of 4 km/hour and reaches there in 30 minutes.

$\mathfrak{\underline{Need\:To\: Find:-}}$

• The distance of the school from his house = ?

${\purple{\underline{\underline{\bf{\pink{Explanation:-}}}}}}$

Here,

• Speed = 4km

• Time = 30 minutes

• Time = $\mathsf {\dfrac{\cancel{30}}{\cancel{60}}\:h}$

• Time = $\sf{\dfrac{1}{2}\:h}$

$\:\:\:\:\dag\bf{\underline \green{Formula\:used\:here:-}}$

$\bigstar{\underline{\boxed{\sf\purple{Distance = Speed \times Time}}}}$

$\:\:\:\:\dag\bf{\underline \blue{Putting\:the\:values:-}}$

$\longrightarrow \sf {Distance\:of\:the\:school = 4\:km \times \dfrac{1}{2}\:h}$

$\longrightarrow \sf {Distance\:of\:the\:school = 2\:km}$

$\:\:\:\:\dag\bf{\underline{\underline \red{Hence:-}}}$

• The distance of the school from his house is 2 km.
