The minute hand of a clock is exactly six inches in length, and the tip of the minute hand has traveled exactly ten inches since noon. To the nearest minute, what time is it?
The minute hand of a clock is exactly six inches in length, and the tip of the minute hand has traveled exactly ten inches since noon. To the nearest minute, what time is it?
The path traveled by the tip of the minute hand over the course of one hour is a circle of radius 
. The circumference of that circle is
.
The tip has traveled 10 inches since noon, so the fraction of the circle traveled is 
,
and the number of minutes that have expired since noon is 
.
Therefore, to the nearest minute, the time is 12:16.

Find the distance between the clock hands when the time is
The first thing you will have to do is determine the degrees that the hour hand is away from the minute hand. To help find the degrees of the hour and minute hand, you have to realize that when the minute hand is at 30 minutes, the hour hand is halfway between the hours of 10 and 11. Using the fact that at 9:00, the hour and minute hands create a 
angle. Knowing that the hour hand is in between 10 and 11, which is HALFWAY between 9 and 12, the hour hand and the 12 create a 
angle. So adding that to the 
the half circle creates from 12 to 6, then the total would be:
Using the degrees and the circumference of a circle, you can find the distance of the arc length with the following formula.

The minute hand represents our radius therefore

What is the distance, in minutes and seconds, between the minute and hour hands of a clock at
The clock face is divided into sixty equal parts, each minute. The minute hand is located on the 20 minute mark at 6:20, the hour hand located between the 30 minute mark and the 35 minute mark. When the minute hand goes all sixty minutes, the hour hand only moves five, so to figure out the location of the hour hand, we look at how much the hour has progressed, in this case 20 minutes, or one third of the hour. So the minute hand has moved one third of the way through the hour, so has the hour hand moved one third of the way through the five minutes, or, five thirds of a minute, which is one and two thirds minute, one minute forty seconds. That puts the hour hand at thirty minutes plus one minute and forty seconds—at 31min 40sec—which is 11min 40sec farther than the minute hand.

Which pair of hands is further apart and by how much? Clock A is pointing at
The distance between A's hands is simple to find, the minute hand is on the 6 at 30 minutes, halfway through the hour and the hour hand is resting just past the 3 at 15 minutes. What the minute hand travels in an hour, the hour hand travels in five minutes, so halfway through five minutes is 
added to 15 minutes puts the hour hand at 17.5 minutes.
To find the distance we subtract 17.5 from 30:
Therefore A's hands have a 12.5 minutes distance.
The distance between B's hands is the same procedure, the minute hand is on the 7 at 35 minutes, 35/60 through the hour, and the hour hand is resting past the 4 at 20 minutes, so 
is added to 20, which is approximately 23 minutes, To find the distance we subtract 23 from the 35:
putting B's hands 12 minutes apart.

A certain clock has a minute hand 12 cm long and an hour hand that is 9 cm long. At 9:00, how far apart are the ends to the two hands of the clock?
A picture will help a bunch for this problem, so we begin by looking at a clock at 9:00
We should notice two things. The first is that by drawing in the distance we wish to find, namely that between the ends of the two hands, we end up with a triangle. Secondly, remembering that a full circle is 360 degrees, we see that the distance between the two hands spans 3 hours, or one fourth of the circle. One fourth of 360 is 90, so the angle between our two hands is a right angle.
We now realize that we have a right triangle, and our desired distance is simply the hypotenuse, which we can name 
. This means we can find our distance by utilizing the Pythagorean Theorem. Plugging our known values in gives
Taking the square root gives our answer.
