 Q. A man sitting in train travelling at the rate of 50 km/hr observes that it takes 9 sec for a goods train travelling in the opposite direction to pass him. If the goods train is 187.5m long. Find its speed
 ✖ A. 40 km/hr ✖ B. 30 km/hr ✖ C. 24 km/hr ✔ D. 25 km/hr

Solution:
Option(D) is correct

Let the speed of goods train be $x$ km/hr.

$(50+x)\times \dfrac{5}{18}=\dfrac{187.5}{9}$

⇒ x= 25 km/hr
