Question
A train overtakes two persons walking along a railway
track. The first one walks at 3.2 Km/h. The other one walks at 4.5 Km/h. The train needs 5.5 and 5.6 second respectively to overtake them. What is the speed of the train if both the persons are walking in the same direction as the train?Solution
Let the speed of train be x km/h
As both the persons are walking in the same direction of train.
so, (x- 3.2) x 5.5 = (x-4.5)x5.6
=> 0.1x = 7.6
=> x = 76 km/h
