Question

A bus travels $160km$ in $4$ hours and a train travels $320km$ in $5$ hours at uniform speeds, then find the ratio of the distance travelled by them in one hour.

Answer 1

A bus travel in $4$ hours $=160km$
$\therefore$ Distance covered by bus in $1$ hour
$=\frac{100}{4}=40km$
A train travel in $5$ hours $=320km$
$\therefore$ Distance covered by train in $1$ hour
$=\frac{320}{5}km=64km$
Ratio in their speed $=40:64=5:8$
