A train 200 m long crosses a platform 300 m long in 25 seconds. What is the speed of the train in km/h?

Topic: Speed, Time &amp; Distance
Subtopic: Trains

A60 km/h

B72 km/h

C80 km/h

D90 km/h

Explanation

Total distance = 200 + 300 = 500 m. Speed = 500 / 25 = 20 m/s. Convert to km/h = 20 * (18/5) = 72 km/h.
