Time, Speed and Distance
A 200 meter train takes 15 sec to cross a man who is walking in the same direction at the speed of 4 km/hr. The speed of the train is: |
48 km/hr 60 km/hr 52 km/hr 55 km/hr |
52 km/hr |
Let the speed of the train be x km/hr The relative speed of the train with respect to the man = (x - 6) km/hr ⇒ (x - 4) = 20015 × 185 (converting m/s to km/hr by multiplying with x185) ⇒ (x - 4) = 40 × 65 ⇒ x - 4 = 48 x = 52 Ans = 52 km/hr |
