Question
Two trains approach each other at 15 kmph and 25 kmph
from 2 places 280 km apart. After how many hours they will meet?Solution
Distance = 280 km Speed of train 1 = 15 km/hr Speed of train 2 = 25 km/hr Relative speed = 15 + 25 = 40 km/hr Therefore, speed = distance/time ⇒ 40 = 280/Time ⇒ Time = 280/40 = 7 hrs
