Please help me with this algebra problem?

Question

Technology. Driving down a mountain, Tom finds that he has descended 1800 ft
in elevation by the time he is 3.25 mi horizontally away from the top of the
mountain. Find the slope of his descent to the nearest hundredth.

Answer 1

Slope= change in elevation/change in horizontal .
So elevation change=- 1800 feet.
Horizontal displacement=3.25 mi*5280ft/mile
You should be able to do the rest.

Answer 2

first you need to change the 3.25 miles to feet. then calculate rise over run
