<u>Answer:</u>
1) Distance traveled by bird = 403 meter
2)Average speed = 1.66 km /hour
3) Zcceleration = 2 
<u>Explanation:</u>
1)  Distance traveled = Speed * Time taken = 31 * 13 = 403 meter.
2)  Average speed = Total distance covered / Time taken for that distance to cover.
     Total distance covered = 2+0.5+2.5 = 5 km
     Time taken = 3 hours
      Average speed = 5/3 = 1.66 km /hour
3)    Acceleration is defined as the rate of change of velocity, so acceleration a = change in velocity/time.
   Change in velocity = 14 - 6 = 8 m/s
    Time = 4 seconds
    So acceleration = 8 / 4 = 2
