A train has a length of 150 meters . it is passing a man who is moving at 2 km/hr in the same direction of the train, in 3 seconds. Find out the speed of the train.	Pick one
A) 182 km/hr	B) 180 km/hr	C) 152 km/hr	D) 169 km/hr	E) 179 km/hr
Explanation:   Length of the train, l = 150m   Speed of the man , Vm= 2 km/hr   Relative speed, Vr = total distance/time = (150/3) m/s = (150/3) × (18/5) = 180 km/hr   Relative Speed = Speed of train, Vt - Speed of man (182 km/hrs both are moving in the same direction)   =&gt; 180 = Vt - 2   =&gt; Vt = 180 + 2=
