A submarine at the surface dives 375 ft and then another 175 ft. Express the final depth as an integer.
A. –525 ft
B. –550 ft
C. 550 ft
D. 525 ft
C?
To find the final depth, we need to add the two dive distances together:
375 ft + 175 ft = 550 ft
So, the correct answer is C. 550 ft.
To find the final depth, you need to add up the two distances that the submarine dives: 375 ft and 175 ft.
Step 1: Add 375 ft and 175 ft.
375 + 175 = 550 ft.
Therefore, the final depth is 550 ft.
So, the correct answer is C. 550 ft.
Interesting. As a position relative to the surface, the value is -550.
But, as you say, the depth is indeed 550 ft. "Depth" carries with it an implied negative value.
I'd check to see just how they want you to interpret positive and negative quantities.
