A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 120 feet below the surface after 40 seconds. What is the scuba diver's rate of change (include the units)?
Find slope(Rate of Change)

Answer 1

Take 2 points

• (10,30)
• (40,120)

Rate of change=Slope:-

`\\ \rm\hookrightarrow m=(y_2-y_1)/(x_2-x_1)`

`\\ \rm\hookrightarrow m=(120-30)/(40-10)`

`\\ \rm\hookrightarrow m=(90)/(30)`

`\\ \rm\hookrightarrow m=3ft/s`

Answer 2

• 3 feet per second

Explanation:

The rate of change is:

• m = the change in depth / the change in time =
• (120 - 30) / (40 - 10) =
• 90 / 30 =
• 3 feet/second
