Two trains are running in opposite directions on parallel tracks. If their speeds are 50 km/h and 58 km/h , find their relative speed.

Correct option is C

Given:

Speed of both the trains = 50km/hr and 58 km/hr

Formula Used:

If the train are running in opposite direction then relative speed is sum of the speeds

Solution:

Relative speed of both trains = 50 +58 = 108km/hr

Speed in metre per second = $$108 \times \frac{5}{18}$$ = 30m/sec
