the diver reaches a depth of 4 meters. it is 11m top to the bottem.

4m

doesn't matter how deep the water is.

i dont know what the answer is

oh wow steve your so smart

To find the change in elevation of the dive, we need to subtract the depth the diver reached from the total distance from top to bottom.

Change in elevation = Total distance - Depth reached

Total distance = 11 meters
Depth reached = 4 meters

Using the formula, we can calculate the change in elevation:

Change in elevation = 11 meters - 4 meters
Change in elevation = 7 meters

Therefore, the change in elevation of the dive is 7 meters.
