A horse starts to chase a dog that has left the stable two hours earlier. The horse runs at an average speed of 2km/hr. It crosses a 10-metre road, two small ponds 3 metres deep, and finally runs along two small streets of 200 metres long. After traveling 6 hrs, 2hrs after sunset, it catches the dog. Compute the speed of the dog in Km/hr?
(a) 20 (b) 22 (c) 16.5 (d) 18.5

• distance travelled by horse=2*6=12
  speed of dog=12/8=1.5
  ans shud b 1.5km/hr
  but i think ques is wrong....if v have avg speed =22km/hr thn v get 16.5 as ans so please chack the question.
