To find the change in height, we need to consider the height from where Ping dove (the platform) to the depth he reached in the water.
- Height of the platform = 10 meters
- Depth reached = 6 meters below the water's surface
To find the change in height, we subtract the depth from the height of the platform:
Change in height = Height of platform - Depth reached Change in height = 10 meters - (-6 meters) = 10 meters + 6 meters = 16 meters
So, the correct answer is 16 meters.
