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.
:
One of the definitions of slope is "Rise/run"
:
Convert miles to ft like the given elevation: 3.25 * 5280 = 17160 ft
:
He is descending so the 1800 ft will be negative:
:
Slope = %28-1800%29%2F17160 = -.104895 or -.10
