Answer: The estimated total change in distance from where they started at the surface. = +29 feet

The total change in distance from where they started at the surface = 29.36 feet

Step-by-step explanation:

Given : The instructor takes the group 51.89 feet below the surface to start.

i.e. -51.89 feet below surface

Then they go up 29.36 feet , represented by 29.36

Here 51.89 ≈ 52

29.36 ≈  29

The estimated total change in distance from where they started at the surface. = +29 feet

The total change in distance from where they started at the surface = 29.36 feet
