Answer:
30 minutes
Step-by-step explanation:
The hiker starts at sea level or 0 feet. He descends 25 feet every minute. This can be written in an equation as so, 0 acting as the starting point, f being feet, and m being minutes:
f = 0 - 25m
This simplifies to:
f = - 25m
We can substitute f in for -750
-750 = - 25m
Now, we divide by - 25 by both sides of the equation
-750 ÷ - 25 = 750 ÷ 25 = 30
30 = m
It would take 30 minutes for the hiker to get to - 750 feet in elevation.
I Hope That This Helps! :)
