average speed 22km/hour, horse crossed 10 mts road and two small pounds with depth 3m, and

it crossed two small street with 200 mts length. After travelling 6 hrs, 2 hours 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.
