      Question

      A spy is 1.8 km ahead of an agent who begins to chase him.

      The agent runs at a speed of 12 m/s, while the spy runs at 8 m/s. How much time will the agent take to catch the spy?
      A 7.5 mins Correct Answer Incorrect Answer
      B 12 mins Correct Answer Incorrect Answer
      C 10.5 mins Correct Answer Incorrect Answer
      D 15 mins Correct Answer Incorrect Answer

      Solution

      ATQ,

      Relative speed = 12 โ€“ 8 = 4 m/s

      Distance = 1.8 ร— 1000 = 1800 metres

      Required time = (1800 / 4) = 450 seconds = (450 / 60) = 7.5 minutes
