360÷12=30°



From 8:00 to 9:40 in the evening, how many degrees does the clock rotate


Every hour is 30 degrees, 8:00 to 9:40 is 1 and 2 / 3 hours, 30 * (1 and 2 / 3) = 50 degrees
Or, if you walk 0.5 ° every minute from 8:00 to 9:40, it will be 100 minutes



When is the clockwise rotation of 120 ° from three points
