Vicky and Vikram start running simultaneously around a
rectangular track of length 840m from the same point at speeds of 40 km/hr and 32 km/hr. When will they meet for the first time anywhere on the track if they are moving in opposite directions?Solution
Relative speed = 40 + 32 = 72 km/hrs Time taken to meet for the first time = length of the track/ relative speed => 840 / (40 + 32) => (840 x 18)/(72 x 5) = 42 sec
