Question

A train is runnin at a speed of 72km\h how far it will go in 7seconds​

Answer 1

Answer:

Given:

Speed of train = 72 km/h

Length of train = 220 metre

Length of platform = 330 metre

Formula used:

Speed = Distance/Time

Speed (in m/s) = Speed (in km/h) × (5/18)

Calculations:

Speed = 72 × (5/18)

⇒ Speed = 4 × 5

⇒ Speed = 20 m/s

Total distance to travel = 220 + 330

⇒ Distance = 550 m

Time taken to cover the distance = Distance/Speed

⇒ 550/20

⇒ 27.5 seconds
