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?

50

Let speed of train starting from station Q = S km/h

Relative speed when moves in opposite direction = (60 + S ) km/h

According to question ,

Speed = \(\frac{275}{2.5}\) = 110 km/h

110 = 60 + S

S = 50 km/h

So , Speed of train starting from station Q is 50 km/h .
