Question

A 200m long train has to cross a platform which is 500m long. If the train is traveling at a speed of 70m/s, how long will the train take to cross the platform?

• A. 10
• B. 20
• C. 30
• D. 40

Answer 1

The correct option is A

10

To cross the platform, the last coach of the train will have to cross the platform.

So, the total distance the train has to travel = ( length of the train + length of the platform ).

Now, the total distance = (200 + 500)m = 700m

Therefore,
$Timetaken=\frac{totaldistance}{speedofthetrain}$
$=\frac{700}{70}$
$=10s$
