At one time the aircraft is 200 m above the surface the submarine is 55 m below the surface and the underwater robotic vehicle is 127 m below the surface what is the distance between the submarine and the aircraft

The aircraft and the submarine are 255 m apart

Step-by-step explanation:

Here, we want to calculate the distance between the submarine and the aircraft

From the question;

The aircraft is 200 m above the surface and the submarine is 55 m below ( this is same as an altitude of -55)

So the distance between the two will be;

200-(-55) = 255 m

-2 is the right
