Question

A scuba divers dove 950 feet below the surface in 19 minutes what integer represents the average rate of change for this dive?

Answer 1

"950 feet in 19 minutes" can be expressed as the rate  (950/19) (ft/min), and is negative because the diver is descending (going downward).

Simplifying, -950/19 (ft/min) = -50 (ft/min)
