How many degrees does the minute hand of the clock turn from 2:15 to 2:30? Find the angle between the hour hand and the minute hand at 2:5? Find the angle between the hour hand and the minute hand at 2:40? Find the angle between the hour hand and the minute hand at 2:48?

How many degrees does the minute hand of the clock turn from 2:15 to 2:30? Find the angle between the hour hand and the minute hand at 2:5? Find the angle between the hour hand and the minute hand at 2:40? Find the angle between the hour hand and the minute hand at 2:48?

The minute hand of the clock turns 15 △ 60 × 30 = 7.5 degrees
The angle between the hour hand and minute hand at 2:05:00 is (2 + 5 / 60) × 30 ° - 5 × 6 ° = 32.5 °
The angle between the hour hand and minute hand at 2:40: 40 × 6 ° - (2 + 40 / 60) × 30 ° = 160 °
The angle between the hour hand and the minute hand at 2:48 am is as follows:
48×6°-(2+48/60)×30°=204°
360°-204°=156°

How many degrees did the minute hand of the clock turn from 2:15 p.m. to 5:30 p.m
Wrong. It's the hour of the clock

(1 / 12 × 3 + 1 / 12 × 4) × 360 = 97.5 degrees

From four o'clock sharp, at least again______ The minute hand and minute hand coincide for the first time

Let's start from 4 o'clock, after X minutes, the hour hand and the minute hand coincide for the first time. From the meaning of the question, we can get: 6x-0.5x = 120, & nbsp; & nbsp; 5.5x = 120, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; x = 21911; a: at least after 21911 minutes, the hour hand and the minute hand coincide for the first time. So the answer is: 21911
