5 m/s
How did we get it?
From the problem we have the following givens:
(a) a dog crossed the park from one side to the other
(b) the total distance from one side of the park to the other side is 80.0 m
(c) the total time the dog spent to cross the park is about 16.0 s
(d) we are looking for the speed (S)
Remember, the formula for speed is:
How to solve it? Substitute the given numerical values for the distance and time to the formula.
We have d=80\ md=80 m and t=16\ st=16 s .
Then,
Therefore, the speed of the dog is 5 m/s.
How is it? Happy learning!

Btw, the figure beside "16.0 s" is a clock. Lol :D
