Question

A bus travels 153 km in 3 hours and a train travels 486 km in 6 hours. Find the ratio of their speeds.

Answer 1

A bus travels $153km$ in $3hours$

Speed of the bus $S_b=\frac{153}{3}$

$S_b=51km/hr$

A train travels $486km$ in $6hours$

Speed of the train $S_t=\frac{486}{6}$

$S_t=81km/hr$

Therefore, the required ratio

$=\frac{S_b}{S_t}$

$=\frac{51}{81}$

$=\frac{17}{27}$

Hence, this is the answer.
