How many seconds will a 500 metre long train take to cross a man walking with a speed of 3 km/hr in the direction of the moving train if the speed of the train is 63 km/hr?	Choose the correct choice.
A) 25
B) 30
C) 40
D) 45
E) 35
Speed of the train relative to man	= (63 - 3) km/hr   = 60 km/hr   =(60 x(5/18))	m/sec   =50/3 m/sec.   Therefore Time taken to pass the man   =(500 x(3/50))sec   = 30 sec.   Answer :30
