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:
Answer & Solution
Correct Answer:
Option
D
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
= $$\frac{{{\text{length of the train}} + {\text{length of platform}}}}{{{\text{Time}}}}$$ = $$\frac{{250 + 250}}{{25}}$$
= 20 m/sec
= 72 km/h
