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. find the total distance traveled by the dog.
plz

7200 m

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

7200 m

d) physical means can be used to separate the components of air.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
