Question
Vicky and Vikram start running simultaneously around a
rectangular track of length 600m from the same point at speeds of 35 km/hr and 25 km/hr. When will they meet for the first time anywhere on the track if they are moving in opposite directions?Solution
Relative speed = 35 + 25 = 60 km/hrs Time taken to meet for the first time = length of the track/ relative speed => 600 / (35 + 25) => (600 x 18)/(60 x 5) = 36 sec
