Question

A goods train 125 meter long passes in 6 seconds a passenger of a train running in the opposite direction at 50 km /hrs what is the speed of the train.

​

Answer 1

Step-by-step explanation:

Speed of the train relative to man = (125/5) m/sec = (25) m/sec.

[(25) x (18/5)] km/hr = 90 km/hr.

Let the speed of the train be 'S' km/hr.

Then, relative speed = (S - 6) km/hr.

S=90 /6

S= 15 km /hr
