1. Circumference of the Circle

* The minute hand travels in a circle.

* The radius of this circle is the length of the minute hand (5 cm).

* Circumference = 2 * π * radius = 2 * π * 5 cm = 10π cm

2. Time for One Revolution

* The minute hand completes one full revolution (circle) in 60 minutes (one hour).

3. Speed Calculation

* Speed is calculated as distance traveled divided by time taken.

* Distance = Circumference = 10π cm

* Time = 60 minutes

* Speed = (10π cm) / (60 minutes) ≈ 0.52 cm/minute

Therefore, the speed of the minute hand is approximately 0.52 centimeters per minute.
