Final answer:
To calculate the change in elevation after a dolphin jumps and dives, we subtract the lowest point below sea level from the highest point above sea level, resulting in a change of 39.3 meters.
Step-by-step explanation:
The question is a physics problem where we are asked to find the change in elevation of a dolphin after jumping and diving. The dolphin jumps 24.5 meters above sea level and then dives 14.8 meters below sea level. To find the change in these levels, we simply calculate the difference between the two positions.
The change in elevation is the dolphin's highest point above sea level minus its lowest point below sea level, which is 24.5 meters - (-14.8 meters) = 24.5 meters + 14.8 meters = 39.3 meters. Thus, the change in the dolphin's elevation from the highest point jumped above sea level to the lowest point dived below sea level is 39.3 meters.
