Question

a boy walks to his school with the speed of kilometre per hour and reach then in 30 minutes find the distance of the school from his house​

Answer 1

distance =speed /time

1000 m ×1/2 hour

= 500 m

Answer 2

$distance = \frac{speed}{time}$

speed = km/h

time = 30mins

30mins=half of a hour

$= \frac{1km}{2}$

1km=1000 metres

$\frac{1000m}{2}$

=500m

therefore your answer is

500meters(half kilometre )

hence the distance of his school from his house is

500metres

hope it helps you.
