GUYS HW PLS HELP WORTH ALL MY POINTS LEFT

A scientist uses a submarine to study ocean life.
She begins 135 feet below sea level.
After traveling down for 8 seconds, she's 210 feet below sea level.

Find the rate of change in the submarine's elevation in feet per second. If necessary, round your answer to the nearest tenth.

Answer 1

9.4

Explanation:

Based on the given conditions, formulate: (210-135) ÷ 8

Calculate the sum or difference:
`(75)/(8)` = 9.375

Rounded: 9.4

Answer 2

approximately 9.4 feet per second

Explanation:

We can use the formula for average rate of change:

average rate of change = (change in elevation) / (change in time)

The change in elevation is 210 - 135 = 75 feet. The change in time is 8 seconds. So:

average rate of change = (75 feet) / (8 seconds) ≈ 9.4 feet/second

Therefore, the rate of change in the submarine's elevation is approximately 9.4 feet per second.
