Question

A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?.

Answer 1

Given Data:

Time is taken = 24 seconds (to pass the pole)

Length of the train = 240 m

To Find:

Time to pass a 650m long platform =?

Solution:

The total distance traveled by train to cross a pole is equal to the length of the train; 240 m.

Distance = 240 m (in case of a pole)

Speed = distance/ time

Speed = 240 m/ 24 seconds

Speed = 10 m/s

So, the speed our train is traveling is 10 m/s.

Now, the time taken by the same train to cross a platform of 650 m can be calculated as,

Total distance = 650 m (platform length) + 240 m (train length)

Total distance = 890 m

Speed = distance/ time

Time = distance/ speed

Time = 890 m / 10m/s

Time = 89 seconds.

So, the time that it will take a train with a speed of 10 m/s and 240 m long to cross a plate form of 650 m is 89 seconds.
