Well, Kate and Harry together are walking 100 meters per minute. Which means it will take them 25 minutes to reach each other (I think).

If the dog is running 120 meters per minute: 120 x 25 = 3,000.

The dog will run 3,000 meters (if he runs constantly to and from the spot that Kate and and Harry started).
