Question

A hiker begins at sea level and descends 25 feet every minute. How long will it take to get to an elevation of -750 feet?

Answer 1

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! :)
