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?

horse travels for 6 hrs at the speed 2km/hr.
thereforeb distance travelled by horse=6*2=12 km
this distance is travelled by dog in 6+2=8hrs
then avg speed of dog=12/8=1.5 km/hr

all the option over there are wrong.all of them are greater than the speed of horse.if it is then it is impossible for the horse to catch the dog
