Question 88357: I have not been in a math class for over 30 years am now taking a math course. Please help me, I would greatly appreciate it. My problem comes from Hutchinson Algebra 6e Chapter 7 page 614 problem 46. This is a word problem. Driving down a mountain, Tom finds that he has descended 1800 feet in elevation by the time he is 3.25 miles horizontally away from the top of the mountain. Find the slope of his descent to the nearest hundredth. I have to show the work.

Driving down a mountain, Tom finds that he has descended 1800 feet in elevation by the time he is 3.25 miles horizontally away from the top of the mountain. Find the slope of his descent to the nearest hundredth.
:
One of the definitions of slope is "Rise over Run"
:
Descending is considered a negative rise so you have -1800ft/3.25mi
:
However, we need them to be in the same units.
:
Convert 3.25 mi to ft: 3.25 * 5280 = 17160 ft
:
Slope = %28%28-1800%29%29%2F17160 = -.104895, that's -.10 to the nearest 100th
