Answer:
172m
Explanation:
From the question above we are told:
The distance of the submarine below the surface = 55m
The distance of the underwater robotic vehicle below the surface = 227m
The distance between the underwater robotic vehicle and the submarine is calculated as:
The distance of the underwater robotic vehicle below the surface - The distance of the submarine below the surface
= 227m - 55m
= 172m
Therefore, the distance between the underwater robotic vehicle and the submarine is 172m
