Answer:
185.1 m/s
Explanation:
The average speed of an object is a scalar quantity telling us how fast is the object moving over a certain distance.
This quantity is calculated as
[tex]v=\frac{d}{t}[/tex]
where
d is the distance covered by the object
t is the time elapsed
v is the average speed
In this problem we have:
d = 1500.0 m is the distance covered by Ken
t = 8.1018 s is the time taken
Substituting into the formula, we find the average speed:
[tex]v=\frac{1500.0}{8.1018}=185.1 m/s[/tex]
