Can You Please Help Me With This Algebra Question?

A deep sea diving bell is being lowered at a constant rate. After 8 minutes, the bell is at a depth of 300 feet. After 35 minutes the bell is at a depth of 2000 feet. What is the average rate of lowering per minute? Round to the nearest hundredth if needed.

    47.3 ft/min

    8x=300ft
    35x=2000ft solve for both x’s and then add them and divide by two to get the average.

    avg. = (2000 – 300)/(35 – 8)
    = 1700 / 27

    No offense meant to you, but you should let whoever set you this question know that its not very well worded: "being lowered at a constant rate", "what is the average rate"

    As it stands however, I cant see how you are supposed to need algebra to solve this. It is simply, as it took 35 minutes to do a total of 2000 feet, its 2000/35 = 57.14 ft/min

    sorry I couldnt be more helpful
