In 2 hours, the minute hand of a clock rotates through an angle of90°180°360°720°

Break Down the Problem

1. Determine how far the minute hand rotates in a complete hour.
2. Calculate the total angle the minute hand rotates in 2 hours.

Relevant Concepts

• The minute hand of a clock completes one full rotation (360 degrees) in 60 minutes (1 hour).

Analysis and Detail

1. Full rotation in one hour:

   • The minute hand completes 360° in 1 hour.

2. Rotation in 2 hours:

   • In 2 hours, the minute hand would rotate: $360° \times 2 = 720°$

Verify and Summarize

The calculation shows that the rotation of the minute hand is 720° in 2 hours, which confirms the findings.

Final Answer

The minute hand of a clock rotates through an angle of 720° in 2 hours.
