Question

A train starts running at a uniform speed of 60 km/h from station P towards station Q. At the same time another train starts running from station Q towards station P. If the distance between the stations P and Q is 275 km and the trains meet in two and a half hours, then what is the speed of the train running towards station P in km/h?
1. 44
2. 40
3. 48
4. 50

Answer 1

Correct Answer - Option 4 : 50

Given:

Distance between P and Q = 275km

Calculation:

Let speed of train running towards station P be a kmph.

Relative speed = a + 60

Then,

⇒ a + 60 = 275/2.5

⇒ a + 60 = 110

⇒ a = 50

∴ speed of train running towards station P is 50 kmph.
