A train 110 metres long is running with a speed of 60 kmph. In what time will it pass a man who is running at 6 kmph in the direction opposite to that in which the train is going?
Answer with explanationAnswer: Option B
Speed of train relative to man = (60 + 6) km/hr = 66 km/hr.
(66*5/18) m/sec = 55/3 m/sec
Time taken to pass the man = (110*3/55)m/sec = 6 sec.
