From a base elevation of 8200ft. a mountain peak in colorado rises to a summit elevation of 14701ft.over a horizontal distance of 15838 ft. Find the grade of the peak.

The grade of the peak is what percent?

(Round to the nearest tenth as needed)

**drwls**, Saturday, October 25, 2008 at 8:07pmThe summit rise is 14701-8200 = 6501 feet. The "grade" is that rise divided by the horizontal distance, expressed as a percent.

Just to quibble a bit, there are no mountains in Colorado that are that high. Grade numbers are usually applied to roads and areas of constant slope, NOT to entire mountains.

Whoever dreamed up this question needs a refresher course in math and geography
