Step-by-step explanation:

A woman takes her pet dog on a walk to a pond which is 4km away. The woman runs with a speed of 2.5 ms-1 while the dog runs with the speed of 4.5ms^-1 towards the pond and returns to the women and then again runs back to the pond continuously until the woman also manages to reach the pond. The total distance traveled by the dog is 7200 m.

Answer 2

7200 m

Step-by-step explanation:

The pond is 4000 meters away. The woman runs at 2.5 m/s. The time it takes her to reach the pond is:

t = 4000 m / 2.5 m/s

t = 1600 s

The dog is running at 4.5 m/s this entire time. So the distance he runs is:

d = 1600 s × 4.5 m/s

d = 7200 m
