Question

Graham is hiking at an altitude of 14,040 feet and is descending 50 feet each minute. Max is hiking at an altitude of 12,500 feet and is ascending 20 feet each minute. How many minutes will it take Graham and Max to meet at the same altitude?

Write an Equation to represent this scenario. Let \displaystyle xx = # of minutes.

Answer 1

Answer:

M=22, hope this helps

Explanation:

Set up Graham's altitude function A(m):

A(m) = 14040 - 50m <-- we subtract for descending

Set up Max's altitude function A(m):

A(m) = 12500 + 20m <-- we add for ascending

Set the altitudes equal to each other to solve for m:

14040 - 50m = 12500 + 20m

We type this equation into our search engine to solve for m and we get:

m = 22

Answer 2

Tbh I don’t even know like wouldn’t you divide 50 by 14040 to find out how long it’ll take?
