Question

18. A hiker was at an elevation of 9,347 feet. Five hours later, he was at 6,587 feet. Find his average change in elevation per minute.

Answer 1

Answer:

Average change in elevation per minute = -9.2 feet/min

Explanations:

Initial elevation = 9347 feet

Final elevation = 6587 feet

Change in elevation = Final elevation - Initial elevation

Change in elevation = 6587 - 9347

Change in elevation = -2760 feet

Change in time = 5 hours

1 hour = 60 minutes

Change in time (in minutes) = 60 x 5

Change in time (in minutes) = 300 minutes

Average change in elevation per minute =

(Change in elevation) / (Change in time)

Average change in elevation per minute = -2760/300

Average change in elevation per minute = -9.2 feet/min
