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 times, we can 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 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
The displacement of the tip of the minute hand can be calculated based on the angle it sweeps. In 30 minutes, the minute hand moves through half of a circle (180 degrees).
