Answer 1

Hello!

Answer:

Jessiah is faster than Malik because 17.33 > 13.33.

Explanation:

To solve this exercise, we will calculate the average speed of each of them, using the formula:

`A_(s) =` Δ
`(s)/(t)`

Let's calculate each average velocity by replacing the values:

Jessiah:
`A^s^{}=(624)/(36) =(312)/(18) =(156)/(9) =(52)/(3)` ≈
`17.33~feet/second`Malik:
`A^s^{}=(720)/(54) =(360)/(27) =(120)/(9) =(40)/(3)` ≈
`13.33~feet/second`

Hope this helps!
