Answer: 1.33
Step-by-step explanation:
Given : Time taken by Sergio to reach the bottom of a pool = 6 seconds
The depth of the bottom of the pool = 8 feet
We know that ,
[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}\\\\=\dfrac{8}{6}\text{feet per second}\\\\=1.33333333333\text{ feet per second}\\\\\approx1.33\text{ feet per second}[/tex]
Hence, the best number to describe Sergio's rate of speed in feet per second is 1.33.
