      Question

      Vicky and Vikram start running simultaneously around a

      rectangular track of length 500m from the same point at speeds of 30 km/hr and 20 km/hr. When will they meet for the first time anywhere on the track if they are moving in opposite directions?
      A 42 sec Correct Answer Incorrect Answer
      B 36 sec Correct Answer Incorrect Answer
      C 48 sec Correct Answer Incorrect Answer
      D 60 sec Correct Answer Incorrect Answer

      Solution

      Relative speed = 30 + 20 = 50 km/hrs Time taken to meet for the first time = length of the track/ relative speed => 500 / (30 + 20) => (500 x 18)/(50 x 5) = 36 sec
