      Question

      A thief and a policeman are 80 km apart. The thief is

      traveling at a speed of 48 km/h, while the policeman is moving at 80 km/h. How far will the policeman travel before he catches up to the thief?
      A 200 km Correct Answer Incorrect Answer
      B 160 km Correct Answer Incorrect Answer
      C 240 km Correct Answer Incorrect Answer
      D 280 km Correct Answer Incorrect Answer
      E 140 km Correct Answer Incorrect Answer

      Solution

      Relative speed = 80 - 48 = 32 km/h Time taken by the policeman to catch the thief = (80/32) = 2.5 hours Therefore, required distance = 80 x 2.5 = 200 km
