Question 58

A scooter travels 120 km in 3 hours and a train 120 km in 2 hours.
Find the ratio of their speeds.
[Hint: Speed = $\frac{\text{Distance travelled}}{\text{Time taken}}$

Answer 1

Distance travelled by scooter in 3 hours = 120 km
Speed of scooter = $\frac{Distance}{Time}=\frac{120}{3}=40km/h$
Distance travelled by train in 2 hours = 120 km
Speed of train = $\frac{120}{2}=60km/h$
$\therefore$ Ratio of their speeds = $\frac{40}{60}=\frac{2}{3}=2:3$ [on dividing numerator and denominator by 20]

Hence, the ratio of speed of scooter to that of train = 2 : 3.
