To calculate the total dive, we need to find the total distance the diver traveled.
The diver starts from a platform that is 11 meters above the water and dives down 4 meters below the water. So, we need to find the sum of these two distances.
To find the total dive, we can use the formula:
Total dive = Distance above water + Distance below water
In this case, the distance above water is 11 meters (the height of the platform) and the distance below water is 4 meters.
Plugging in the values into the formula, we have:
Total dive = 11 meters + 4 meters
Therefore, the total dive is 15 meters.
