Question

A car is travelling at a uniform speed of $75$ km/hr. How much distance will it cover in $20$ minutes ?

(a) $25$ km (b) $15$ km (c) $30$ km (d) $20$ km

Answer 1

Answer : (a)

Distance covered $75$ km

Time taken $60$ min. $20$ min.

Less distance will be covered in less time.

By direct proportion,

$75:x::60:20$

$x=\frac{75\times 20}{60}=25$

$\therefore$ Distance covered = $25$ km
