Two trains are moving in the same direction at the speed of 36 km/hr and 48 km/hr. The time taken by faster to cross a man sitting in the slower train is 33 seconds. What will be the length of the faster train ?
Answer & explanation
Correct answer: option 3
Relative speed ( when both trains moves in same direction ) = 48 - 36
= 12 km/h
x km/h = x × \(\frac{18}{5}\) m/sec
= 12 × \(\frac{18}{5}\) m/sec
Time taken = 33 sec
Distance = 12 × \(\frac{18}{5}\) × 33 = 110m
