Question
Vicky and Vikram start running simultaneously around a
rectangular track of length 650m from the same point at speeds of 40 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? STSolution
Relative speed = 40 + 25 = 65 km/hrs Time taken to meet for the first time = length of the track/ relative speed => 650 / (40 + 25) => (650 x 18)/(65 x 5) = 36 sec
