Two trains approach each other at 19 kmph and 23 kmph from 2 places 210 km apart. After how many hours they will meet?
Distance = 210 km Speed of train 1 = 19 km/hr Speed of train 2 = 23 km/hr Relative speed = 19 + 23 = 42 km/hr Therefore, speed = distance/time ⇒ 42 = 210/Time ⇒ Time = 210/42 = 5 hrs
