You can put this solution on YOUR website! A deep sea diving bell is being lowered at a consent rate. After 8 minutes, the bell is at a depth of 600 feet. After 40 minutes the bell is at a depth of 1500 feet. What is the average rate of lowering per minute?
------------------
You have 2 points: (8,600) and (40,1500)
---
average rate = slope = (1500-600)/(40-8) = 900/32 = 450/16 = 28.125 ft/min
