Question 16

# Two trains are running in opposite directions with the same speed. If the length of each train is 486 metres and they cross each other in 27 seconds, then what is the speed (in km/hr) of each train?

Solution

Let speed of each train = $$x$$ km/hr

Since, the trains are running in opposite directions, then total length = 486 m

Speed = $$\frac{486}{27}=18$$ m/s

=> Speed (in km/hr) = $$18\times\frac{18}{5}=64.8$$

=> Ans - (C)
