Marks: +1, -0

A train travelling at the speed of 60 km/hr crosses a platform in 20 seconds. What is the length of the train?

Solution:

Distance travelled in 20 sec. = 60 ×

5/{18}

× 20 =

{1000]/3

m
Here, Length of platform + Length of train =

{1000}/3

m
But, length of platform is not given, so length of train cannot be determined.
