A train crosses a platform 100 m long in 60 seconds at a speed of 45 km/hr. The time taken by the train to cross an electric pole is:
1 minute
52 sec
1.5 minute
Data inadequate
8 sec
Total Distance covered = 45 x 5/18 x 60 => 750
Trains Length = 750 - 100 => 650
Time taken by train to cross electric pole = 650/(45 x 5/18) => 52 seconds
