A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is

A. 45 km/hr

B. 50 km/hr

C. 54 km/hr

D. 55 km/hr

Correct Answer : B.


Speed of the train relative to man = 12510 m/sec    = 252 m/sec.= 252 x 185 km/hr   = 45 km/hr.  Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr.∴ x - 5 = 45     ⇒x = 50 km/hr.
