Question

Find the approximate angle between the minute hand and the hour hand of a 12-hour clock when the time is 9:25.

• A. 150 degrees
• B. 100 degrees
• C. 190 degrees
• D. 132.5 degrees

Answer 1

Answer:

D. 132.5 degrees

The angle between the minute hand and the hour hand at 9:25 is $132.5^\circ$.

Shortcut Formula Method

You can also use the standard clock angle absolute formula:
$\text{Angle} = \left\vert{} 30H - \frac{11}{2}M \right\vert{}$
Substitute $H = 9$ and $M = 25$:
$\text{Angle} = \left\vert{} 30(9) - \frac{11}{2}(25) \right\vert{} = \vert{}270 - 137.5\vert{} = 132.5^\circ$
