A submarine is searching for underwater features. It is accompanied by a small aircraft

and an underwater robotic vehicle.

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 227 m below the surface.

a.

What is the difference in height between the submarine and the aircraft?

Answer :

Answer: The required difference is 255 m .

Step-by-step explanation:

Since we have given that

Distance at which the aircraft is above the surface = 200 m

Distance at which the submarine is below the surface = 55 m

Above the surface is represented as positive number i.e. (+) 200 m

Below the surface is represented as negative number i.e. (-) 55 m

So, the difference in height between the submarine and the aircraft is given by

[tex]+200-(-55)\\\\=200+55\\\\=255\ m[/tex]

Hence, the required difference is 255 m .

a. The difference in height between the submarine and the aircraft is 255 m

  • The calculation is as follows:

= Above the service - (below the surface)

= 200 - (-55)

= 200 + 55

= 255
