Question 88357
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 = {{{((-1800))/17160}}} = -.104895, that's -.10 to the nearest 100th
