Adeep sea diving bell is being lowered at a constant rate. after 10 minutes, the bell is at a depth of 600 ft. after 40 minutes the bell is at a depth of 1 comma 700 ft. what is the average rate of lowering per minute? round to the nearest hundredth.

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

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
