Clock. What is the measure of the angle (in degrees) that the minute hand traces in 20 minutes?
Based on the number of degrees that 60 minutes is, we can infer that 20 minutes will be 120°.
A total revolution around a clock is 360° and this translates to 60 minutes.
This means that every minute is:
= Number of degrees in total / Number of minutes in revolution
= 360 / 60
= 6° per minute
If there are 20 minutes, the number of degrees is:
= 6 x 20
= 120°
In conclusion, 20 minutes on the clock is 120°.
