<h2>Average rate of lowering per minute = 36.67 ft/min</h2>

Step-by-step explanation:

After 10 minutes, the bell is at a depth of 600 ft

After 10 minutes

Depth of bell = 600 ft

After 40 minutes the bell is at a depth of 1,700 ft.

After 40 minutes

Depth of bell = 1700 ft

Time gap = 40 - 10 = 30 minutes

Depth fallen = 1700 - 600 = 1100 ft

We have

Depth fallen = Average rate of lowering per minute x Time gap

1100 = Average rate of lowering per minute x 30

Average rate of lowering per minute = 36.67 ft/min

A deep sea diving bell is being lowered at a constant rate. After 10 ​minutes, the bell is at a depth of 600 ft. After 40 minute
