Question

Another submarine’s descent can be represented as = ― 240, where is the

elevation and is time in hours. How long will it take this submarine to make the descent?

Answer 1

It will take approximately 8.75 hours for the submarine to make the descent to the seafloor 2,100 feet below the surface.

The equation for the submarine's descent is y=−240x, where y is the elevation and x is the time in hours. To find out how many hours (x) it will take for the submarine to descend to 2,100 feet below the surface, you can set up the equation:

-240x = -2,100

Now, solve for x

x = 2100 / 240

x = 8.75

So, it will take approximately 8.75 hours for the submarine to make the descent to the seafloor 2,100 feet below the surface.

Another submarine’s descent can be represented as y = -240x, where y is the elevation and x is time in hours. How many hours will it take this submarine to make the descent to the seafloor 2,100 feet below the surface?
