Question

A bus travels $126km$in $3$ hours and a train travels $315km$ in $5$ hours$.$ Find the ratio of their speeds$.$

Answer 1

Step $1:$ To find the ratio of their speeds

Given A bus travels $126km$ in $3$ hours and

A train travels $315km$ in $5$ hours.

Step $2:$ Find the speed of bus

Speed $=\frac{Dis\tan ce}{Time}$

Speed of the bus $=\frac{126}{3}$

$=42$ $km/h$

Step $3:$ Find the speed of train

Speed of the train $=\frac{315}{5}$

$=63$ $km/h$

Step $4:$ Now find the ratio of their speeds

Required Ratio$=\frac{42}{63}$

$=\frac{6}{9}$

$=\frac{2}{3}$

Hence, the ratio of their speed is $2:3$
