A scuba diver descended a total of 56 feet below the
surface of the ocean in 4 minutes. If the diver
descended at a constant rate, which integer gives the
feet descended each minute?
A –14          B –7           C 7          D 14
Read the Item
You need to find the feet per minute the diver descended.
Represent the total number of feet below the surface of
the ocean using –56.
Solve the Item
–56 ÷ 4 = –14
