Question

A train crossed a platform in 25 seconds. The length of the platform is 240 metres. What is the
length of train?

Answer 1

I think the question is wrong

Answer 2

The length of the platform is 240 metres. The  length of train cannot be determined as data is insufficient

SOLUTION:

Given that, a train crossed a platform in 25 seconds.  

The length of the platform is 240 metres.  

We have to find what is the length of train?

Now, we know that, distance = speed x time.

Here in our problem, we given distance and time. But there is no mention about speed.

Since, the speed of the train is not mentioned, we cannot determine the speed of train.

Hence, we can’t determine the length of train as data is insufficient.
