A group of hikers are descending a mountain at a rate of 400 feet per hour. Which expression shows the distance they descend, e, after h hours? Answer Choices e=400+h e=400*h e=400:h e=400-h

First, note that the speed is given by the distance traveled divided by the time spent to travel that distance. Using the given values and variables in the question, we have,

speed = 400

distance = e

time = h

Thus, the expression that shows the distance the group of hikers descend, e, after h hours is e=400*h.
