Question

The maximum speed of a train is 80 km/h. It takes 10 hours to cover a distance of 400 km. Find the ratio of its maximum speed to its average speed.​

Answer 1

Answer:

The train's maximum speed= 80 km/hr

Average speed = total distance travelled

total time taken

The train's average speed= 400km = 40km/hr

10 hours

ratio of maximum speed to average speed= maximum speed : average speed

80km/hr : 40km/hr

= 2:1

Answer 2

Answer:

2:1

Explanation:

Maximum speed of the train = 80km/h

Average speed of the train = Total distance / total time taken

400 / 10 = 40km/h

Ration of maximum speed to its average speed is

80:40

2:1
