Agra and Delhi are 160 km apart. A train leaves Agra for Delhi and at the same time another train leaves Delhi for Agra. Both the trains meet 5 hrs after they start moving. If the train travelling from Agra to Delhi travels 6 km/hr faster than the other train, find the speed of the faster train?

Correct Answer: 19 kmph

Explanation:

Let the speed of the slower train = p kmph


ATQ,


Speed of the faster train = (p + 6) kmph


Then,


(p + p + 6) x 5 = 160


10p + 30 = 160


10p = 130


p = 13 kmph


Then, speed of the faster train = p + 6 = 13 + 6 = 19 kmph.
