Question

a diver descended 38.27 feet in 8.9 minutes. What was the divers average change in elevation per minute

Answer 1

Average rate of change = (amount of change) / (time for the change)

= (-38.27 ft) / (8.9 minutes)

= (-38.27 / 8.9) (feet/minute)

= - 4.3 feet per minute

Answer 2

You would just divide 38.27 by 8.9 and get 4.348 ft/minute.
