Question

At one point during the hike, Noe is at an elevation of 453 feet. After descending at a rate of 50 feet per

minute, she reaches an elevation of 146 feet.
How long does the descent take?

Answer 1

6.14 minutes or 6 minutes & 8.4 seconds

Explanation:

Initial elevation: 453 ft

Final elevation: 146 ft

Difference in elevation: 453 ft - 146 ft = 307 ft

speed = 50 ft/min

speed = distance/time

time * speed = distance

time = distance/speed

time = (307 ft)/(50 ft/min)

time = 6.14 minutes = 6 minutes + 0.14 * 60 seconds

time = 6.14 minutes = 6 minutes + 8.4 seconds
