Answer:
8
was the average velocity of the dog while he was chasing the squirrel
Step-by-step explanation:
Speed is a change of position of a body over time. Then the speed is defined as the amount of space traveled per unit of time with which a body travels in a certain direction and direction.
Its unit of measure in the International System (S.I.) is the meter per second (m/s)

In this case you know that:
Then, the change in time from 9 - 10am is 1 hour.
- Distance traveled = 8 miles north
The dog chased the squirrel for 1 hour a distance of 8 miles and you can assume that his speed was constant.
Finally:



8
was the average velocity of the dog while he was chasing the squirrel
