Length of a minute hand of a clock is 4.5 cm. Find the average velocity of the tip of minute's hand between 6 A.M. to 6.30 A.M. & 6 A.M. to 6.30 P.M.

Explanation

To find the average velocity of the tip of the minute hand of a clock between the specified time intervals, we will follow these steps:

### Step 1: Understand the Problem
We need to calculate the average velocity of the tip of the minute hand of a clock for two different time intervals: from 6 A.M. to 6:30 A.M. and from 6 A.M. to 6:30 P.M. The length of the minute hand is given as 4.5 cm.

### Step 2: Calculate the Displacement for 6 A.M. to 6:30 A.M.
1. **Position at 6 A.M.**: The minute hand points at 12 (0 degrees).
2. **Position at 6:30 A.M.**: The minute hand points at 6 (180 degrees).
