Calgary Tower Problem

The revolving restaurant at the top of the Calgary Tower has two motors which move the restaurant.   The motor at lunch completes one revolution every 45 minutes while the motor at dinner takes one hour to make a complete revolution.   At lunchtime, how many degrees does the restaurant revolve in one hour?

Solution to the Problem:

The answer is 480 degrees.

Set up a proportion: 360 / 45 = x / 60 and solve for x.
