Ben and cam are scuba diving. Ben is 15 meters below the surface of the water. Can is 4 meters above Ben. What is cams position relative to the surface of the water?

Cam's position relative to the surface of the water would be 15 meters - 4 meters = <<15-4=11>>11 meters below the surface.

To determine Cam's position relative to the surface of the water, we need to calculate it by adding his distance above Ben to Ben's depth below the surface.

Given:
Ben is 15 meters below the surface.
Cam is 4 meters above Ben.

To find Cam's position relative to the surface:
Cam's position = Ben's depth below surface + Cam's distance above Ben

Cam's position = 15 meters + 4 meters = 19 meters

Therefore, Cam's position relative to the surface of the water is 19 meters.
