What will be the angle covered by minute hand in one minute?

Question

Accepted Answer

The correct option is 4:
To solve this problem, we need to understand how the minute hand moves on a clock face.
A clock face is a circle, which measures $360^{\circ}$.
The minute hand completes one full rotation ($360^{\circ}$) in 60 minutes.

We want to find the angle covered by the minute hand in one minute.
Since the minute hand covers $360^{\circ}$ in 60 minutes, the angle covered in 1 minute can be calculated as follows:
$$ \text{Angle per minute} = \frac{\text{Total angle of a circle}}{\text{Total minutes in one rotation}} $$
$$ \text{Angle per minute} = \frac{360^{\circ}}{60 \text{ minutes}} $$
$$ \text{Angle per minute} = 6^{\circ} \text{ per minute} $$
Therefore, the minute hand covers an angle of $6^{\circ}$ in one minute.

The incorrect option is 1: $1^{\circ}$ is incorrect because if the minute hand moved $1^{\circ}$ per minute, it would only cover $60^{\circ}$ in an hour, not a full $360^{\circ}$.
The incorrect option is 2: $60^{\circ}$ is incorrect because if the minute hand moved $60^{\circ}$ per minute, it would complete a full circle ($360^{\circ}$) in just 6 minutes, which is not how a clock works. This value might be confused with the number of minutes in an hour.
The incorrect option is 3: $30^{\circ}$ is incorrect because if the minute hand moved $30^{\circ}$ per minute, it would complete a full circle ($360^{\circ}$) in 12 minutes. This value represents the angle between two consecutive numbers on a clock face (e.g., from 12 to 1).
