Part A.)
12.1 / 2.2 = 5.5
So, the elevation of Winston's house is 5.5 times greater than the elevation of the ocean at 2 p.m.
Part B.)
My apologies if any of the following equations is not the right number, I had looked up the equation for the right number.
12.1 x 3.5 = 42.35
So the elevation of Tammy's house is 42.35.
Part C.)
42.35 / 2.2 = 19.25
the elevation of Tammy's house is 19.25 times greater than the elevation of the ocean.
Part D.)
Had to look for the number again. Next time, could you possibly make sure that all of the numbers are here? It makes it a lot easier.
-2.5 x 20.2 = -50.5
Winston reached an elevation of -50.5 feet.
Part E.)
-50.5 / 2 = -25.25
He had stopped at -25.25.
Again, my apologies if some numbers are incorrect. You did not give them, so I went looking for them.
