Final answer:
The revolution of the hour hand from 12 to 5 on a clock is greater than 1 right angle because it covers an angle of 150 degrees, and a right angle is 90 degrees.
Step-by-step explanation:
The question at hand asks whether the revolution of the hour hand from 12 to 5 on a clock is more than 1 right angle. A right angle is 90 degrees. When the hour hand moves from 12 to 3, it covers a quarter of the clock, which is equivalent to one right angle (90 degrees). Therefore, continuing to move from 3 to 5 encompasses more than 1 right angle since each hour on the clock represents 30 degrees (360 degrees divided by 12 hours). Specifically, the hour hand covers 5/12 of the full circle by the time it reaches the 5, resulting in an angle of 5 x 30 degrees = 150 degrees, which is greater than 90 degrees.
