Two trains approach each other at 20 kmph and 25 kmph from 2 places 225 km apart. After how many hours they will meet?
Distance = 225 km Speed of train 1 = 20 km/hr Speed of train 2 = 25 km/hr Relative speed = 20 + 25 = 45 km/hr Therefore, speed = distance/time ⇒ 45 = 225/Time ⇒ Time = 225/45 = 5 hrs
