Question

The maximum speed of a train is 90 km/h . It takes 10 hours to cover a distance of 500
km. Find the ratio of its average speed to maximum speed.

Answer 1

Step 1: Given Data:

The maximum speed of a train is $\text{=90 km/h}$

Total distance = $500km$

Time taken = $10h$

Step 2: Ratio of average and maximum speed

$AvgSpeed=\frac{TotalDistance}{Totaltimetaken}=\frac{500km}{10h}=50km{h}^{-1}$

The ratio of average speed and max speed $=\frac{50}{90}=5:9$
