A diver is swimming at an elevation of -40 feet relative to sea level. The sea floor is 2 3/4 times deeper than the diver: What is the elevation of the sea floor relative to sea level?

Answers

Answer:

-110 feet

Step-by-step explanation:

the elevation of the sea floor relative to sea level can be found by muktiplying the divers elevation by the given factor

to calculage the elevation of the sea floor, we first need to find the elebation of the diber relativeto sea level. Given that the diver's elevation is -40 feet, we can use this as our starting point.

to find the elevation of the sea floor level, we multiply the divers elevation ny 1 3/4. Let's convert 2 3/4 to make an improper fraction to make the calculation easier

2 3/4 is equivalent to (2*4+3) / 4= 11

-40* 11/4 = 440/4 = -110 feet.

therefore the elevation of the sea level is -110 feet
