Answer:
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: [tex]\boxed{S=\dfrac{d}{t}=\dfrac{distance}{time}}[/tex]
How to solve it? Substitute the given numerical values for the distance and time to the formula.
We have [tex]d=80\ m[/tex] and [tex]t=16\ s[/tex].
Then, [tex]S=\dfrac{d}{t}=\dfrac{80\ m}{16\ s}=\bold{5\ m/s}[/tex].
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
