Q: A 200 m long train passes a motorcycler, running in the same direction at 12 km/hr, in 15 second and a jeep travelling in the same direction in 20 s. At what speed is the car travelling (length of both the motorcycler and jeep is negligible)? 3676 0

Answer : 4. "24 kmph"
Explanation :

Answer: D) 24 kmph Explanation: Let the speed of the train be 'S' kmph From the given data, Distance = Length of train = D = 200 mts = 200 x 18/5 kms Time = 10 sec given speed of the motorcycler = 12 kmph Relative speed as they are moving in the same direction = (S - 12) kmph (S- 12)┬а=┬а200┬аx┬а18515S┬а-┬а12┬а=┬а48S┬а=┬а60┬аkmph┬а Hence, the speed of the train = S = 60 kmph Now, Let the speed of the jeep be 'x' kmph 60┬а-┬аx┬а=┬а200┬аx┬а1852060┬а-┬аx┬а=┬а36x┬а=┬а60┬а-┬а36x┬а=┬а24┬аkmph ┬а Therefore, the speed of the jeep = x = 24 kmph.
