Question

The distance between two station is 200 km .A train takes 4 hours to cover this distance .Calculate the speed of the train

Answer 1

The speed to f the train is 50 km per hour

Answer 2

The speed of the train between two stations is 50km/hr or 13.89m/s.

• Speed is the rate of change of distance traveled by body with respect to time.
• Speed = distance traveled/ time taken
• It's units are km/hr or m/s.
• Given,

         Distance between two stations = 200km

     ⇒ Distance traveled by train = 200km

          Time taken to cover the distance = 4hrs

• Therefore, speed of the train = 200km/4hrs

                                                         = 50km/hr

• If we want to cover the units of speed from km/hr to m/s then we need to multiply it  1k/1hr = 1000m/3600s = 5/18.
• Hence, the speed of train in m/s = 50*5/18 = 13.89m/s.
