Wait — 720 / 24 = 30 → so 30 rotations per hour equivalent. But let’s accept the given: minute gear rotates 720 times in 24 hours → rotations per hour = 720 / 24 = 30.

Understanding Gear Rotations: Why 30 Rotations Per Hour Explains the 720-7200 Connection in Mechanical Systems When analyzing mechanical systems—especially gears, motors, or industrial machinery—rotational speed is a foundational parameter. One common calculation involves converting total revolutions over time into rotations per hour. Take this real-world example: the minute gear rotates 720 times in 24 hours, which translates to 30 rotations per hour. But why does this 30-rev/hr figure matter, and how does it unlock insights into gear mechanics? ### The Math Behind Rotational Motion At first glance, dividing 720 by 24 reveals a straightforward calculation:
