Calculating the Movement of the Hour Hand

To calculate the movement of the hour hand on a clock, we can use the following formula:

degrees = (hours * 30) + (minutes * 0.5)

Where: - hours is the current hour on the clock - minutes is the number of minutes past the hour - 30 represents the degrees covered by the hour hand in one hour - 0.5 represents the additional degrees covered by the hour hand for every minute

Calculation

Given that the hour hand starts at a whole hour and moves for 45 minutes, we can calculate the movement of the hour hand as follows:

degrees = (1 * 30) + (45 * 0.5)

Result

Using the formula, we find that the hour hand will move 67.5 degrees after 45 minutes.

This calculation is based on the standard movement of the hour hand on a clock, where it moves at a constant rate of 0.5 degrees per minute in addition to the 30 degrees it covers in an hour
