Sergio dives into the water and it takes him 6 seconds to reach the bottom of a pool that is 8 feet deep. What is the best numbe

marta [7]

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 ,

$\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}\\\\=\dfrac{8}{6}\text{feet per second}\\\\=1.33333333333\text{ feet per second}\\\\\approx1.33\text{ feet per second}$

Hence, the best number to describe Sergio's rate of speed in feet per second is 1.33.
