Question
What is the angle between the two hands of a clock at 4:20? a.0° b.5° c.10° d.20
Solution
To find the angle between the two hands of a clock at 4:20, we need to determine the positions of the hour and minute hands.
-
The hour hand:
- At 4:00, the hour hand points directly at the 4 on the clock face.
- From 4:00 to 4:20, the hour hand moves a fraction of the way between the 4 and the 5.
- Since there are 12 hours on a clock face, each hour mark represents 30 degrees (360 degrees divided by 12).
- Therefore, from 4:00 to 4:20, the hour hand moves (1/3) * 30 degrees = 10 degrees.
-
The minute hand:
- At 20 minutes past the hour, the minute hand points directly at the 4 on the clock face.
- Since there are 60 minutes in an hour, each minute mark represents 6 degrees (360 degrees divided by 60).
- Therefore, at 20 minutes past the hour, the minute hand moves 20 * 6 degrees = 120 degrees.
-
The angle between the two hands:
- To find the angle between the hour and minute hands, we subtract the smaller angle from the larger angle.
- In this case, the hour hand has moved 10 degrees and the minute hand has moved 120 degrees.
- The angle between the two hands is 120 degrees - 10 degrees = 110 degrees.
Therefore, the angle between the two hands of a clock at 4:20 is 110 degrees.
