After traveling 6 hrs, 2hrs after sunset it got dog. compute the speed of dog?**Ans:** As we have speed and travel time of horse, we can get distance travelled by it…

Hence d = 22*6 = 132km,

Exactly this 132km was travelled by dog in 8 hours (as it started two hours earlier).

Hence speed of dog = 132/8 = 16.5km/hr**Ans:16.5km/hr**.
