Question

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 number to describe Sergio's rate of speed in feet per second?

Answer 1

Answer: 1.33

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}=\frac{\text{Distance}}{\text{Time}}\\\\=(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.
