Discussion :: Problems on Trains

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 : Option B
Explanation :
Speed of train relative to man = (60 + 6) km/hr = 66 km/hr.
=  \([ 66 * \frac { 5 } { 18 } ]\)  m/sec  
= \([\frac { 55 } { 3 }]\)  m/sec.  
Time taken to pass the man = [\( 110 *\frac { 3 } { 55 } ]\)  sec = 6 sec.
