Q:
A) 36 kmph | B) 32 kmph |
C) 29 kmph | D) 24 kmph |
Answer: D) 24 kmph
Explanation:
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
Hence, the speed of the train = S = 60 kmph
Now,
Let the speed of the jeep be 'x' kmph
Therefore, the speed of the jeep = x = 24 kmph.
