If a hiking trail is 5.75 miles long and spans elevations from 680 feet to 877
feet. Find the gradient. Hint: gradient = slope = rise/run= change in elevation /horizontal
distance. The numbers in the word problem correspond to line C in the map above with question
12. The gradient of line C = (877-680)/5.75 and the units are feet/mile-use your calculator to
solve for line C's gradient.
