A diver begins at 140 feet below sea level. She descends at a steady rate of 7 feet per minute for 4.5 minutes. Then, she ascends 112.2 feet. What is her current depth?

-45.3 feet depth.

She descends at a steady rate of 7 feet per minute for 4.5 minutes. Then, she ascends 112.2 feet.

While minus sign shows the descent under the water with the water surface as a starting point. Initial depth of diver under the water

The diver descends 5 feet per minute for 3.5 minutes. Now add all the terms below as a numerical expression.

Current Depth of Diver after he descends 5 feet for 3.5 minutes and ascends 122.2 feet after. By taking the initial depth of the diver from which we add or subtract the changes made when he ascends or descends into the water to get the current depth.

Where do deep currents occur?

Thus, deep currents generally occur in the higher latitude regions of the Earth, such as North Atlantic Deep Water and Antarctic Bottom Water, and from these frigid poleward regions, the deep currents flow at a relatively slow pace towards the equator.

Answer: The answer is -45.3 feet depth.

Step-by-step explanation:  While minus sign shows the descend under the water with water surface as starting point. Initial depth of diver under the water

Diver descends 5 feet per minute for 3.5 minutes. Now adding all the terms a below as a numerical expression.

Current Depth of Diver after he descends 5 feet for 3.5 minutes and ascend 122.2 feet after. By taking the initial depth of diver from which we add or subtract the changes made when he ascends or descends in the water to get the current depth.
