Question

The difference in elevation of a helicopter and a submarine is 18 meters. The elevation of the submarine is -7 meters. Write and solve an equation to find the elevation h (in meters) of the helicopter.

A) h = 25 meters

B) h = 11 meters

C) h = 18 meters

D) h = -25 meters

Answer 1

The elevation of the helicopter is 25 meters. We found this by adding the submarine's negative elevation to the difference in elevation between the helicopter and the submarine.

Step-by-step explanation:

The question asks us to find the elevation of the helicopter given that the difference in elevation between the helicopter and the submarine is 18 meters, and the submarine's elevation is -7 meters. To find the elevation of the helicopter (h), we can set up the equation h - (-7) = 18. Solving for h, we add 7 to both sides of the equation, which gives us h = 18 + 7. Therefore, h = 25 meters, and the correct answer is A) h = 25 meters.
