Can someone please explain and show me how to figure out the degrees between the hour hand and the minute hand when the time is 1:40.

What up

The easiest way to do that is by realizing that the clock's circunference has 360 degrees. Divide this by 12 hours marked in the clock and you get 30 degrees for each hour. If the hour hand is at 1 o'clock, that is 30 degrees from the 12 o'clock. If the minute hand is at 40 then that means the hand is pointing at the number 8, which is 30 degrees X 8 = 240 degrees.

The angle between them is from 240 degrees (40 minutes) all the way to 360 degrees (12 o 'clock) + 30 degrees (1 o'clock).
So 150 Degrees is the smallest angle between them.

Find out the degrees between the hour hand and the 12 hour position. Do the same for the minutes hand. Then subtract those two.

Oh right, I see what you are saying roro5611235. You need to see how much the hand that marks the hour has moved by the time the minute hand points at 40 minutes... I overlooked that fact, sorry.

I guess to figure that out you used percentages or rule of three, and after the calculations you realized that the hour hand moves 20 degrees when the minute hand travels 40 minutes.

So to the last answer I gave you that was 150 degrees you add that extra 20 degrees mentioned above. The angle is 170 between them.

Good thing you pointed that out.
