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

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

Hence, the required difference is 255 m .
