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) = 200 x 18515S - 12 = 48S = 60 kmph Hence, the speed of the train = S = 60 kmph Now, Let the speed of the jeep be 'x' kmph 60 - x = 200 x 1852060 - x = 36x = 60 - 36x = 24 kmph Therefore, the speed of the jeep = x = 24 kmph.
