If a 250 m long train crosses a platform of same length as that of the train in 25 seconds, then the speed of the train is:
A. 150 m/sec
B. 200 m/sec
C. 20 km/h
D. 72 km/h
Answer: Option D
Solution (By Examveda Team)
Speed of train= $$\frac{{{\text{length of the train}} + {\text{length of platform}}}}{{{\text{Time}}}}$$ = $$\frac{{250 + 250}}{{25}}$$
= 20 m/sec
= 72 km/h
