A diver begins at sea level and dives down 200 feet. He ascends at a steady rate of 121/3 feet per minute for 4.5 minutes. This depth is represented by the numerical expression: - 200 + 121 3 (4.5) Simplify the expression using the order of operations. What is the diver's depth? - 200 + 37 3 (4.5) - 200 + 55.5

Answer: The divers depth is 144.5 feet below sea level. Or - 144.5 feet.

To find this answer, you have to plug in 4.5 into the given equation.

The steps will look like this. I changed 12 and 1/3 to 37/3

-200 + (37/3) (4.5)

-200 + 55.5

-144.5

This is the depth of the diver after 4.5 seconds.
