To find the change in height, we need to calculate the difference between the starting height (the platform) and the lowest point reached (the depth in the water).
Starting height (platform) = 10 meters
Depth reached = 6 meters (below the surface of the water, so this is -6 meters in relation to the platform height)
Change in height = Height at the platform - Depth reached Change in height = 10 - (-6) Change in height = 10 + 6 Change in height = 16 meters
So, the correct response is 16 meters.
