Question

Two trains are moving in the same direction at 50 km/hr and 30 km/hr. The faster train crossed a man in the slower train in 18 seconds.Find the length of the faster train?.

• A. 80 m
• B. 90 m
• C. 100 m
• D. Can't be determined

Answer 1

The correct option is C 100 m

We know that,

Fast train is $50$km/h

And slow train is $30$ km/h

Then,

The length of the faster train is

$=\left(50-30\right)\times \frac{5}{18}\times 18$ {Cancel $18$ by $18$}

$=100m$

Then,

Option $C$ is correct answer.
