Final answer:
The average angular velocity cannot be determined with the given data.
Step-by-step explanation:
To find the diver's average angular velocity during a dive, we need to calculate the change in angle covered by the diver and divide it by the time taken. In this case, the diver makes 1.5 revolutions, which is equal to 1.5 x 2π radians (since 1 revolution = 2π radians). The time taken for the dive is not given, so we cannot calculate the average angular velocity without that information. Therefore, the answer to the question cannot be determined with the given data.
