To find the difference in altitudes between the scuba diver at -28 meters and the shark at -65 meters, you need to subtract the altitude of the scuba diver from the altitude of the shark. This can be represented as:
Altitude of shark - Altitude of scuba diver
Substitute the given altitudes into the expression:
-65 meters - (-28 meters)
Remember that subtracting a negative number is equivalent to adding the positive value:
-65 + 28
Simplify the expression by adding the numbers:
-37 meters
Therefore, the difference in altitudes between the scuba diver at -28 meters and the shark at -65 meters is 37 meters.
