  2. relative speed is 6+6 = 12 mph. So, to cover 36 miles, time taken is 36/6= 6 hours. In this much time, the pigeon can travel maximum of 72 miles with a speed of 18mph assuming the time taken for reversing the direction is zero.

  3. time taken = 36/12 = 3 hours

    distance traveled by pigeon in 3 hours = 54 miles.
