For this question, we are asked to figure out how far a minute hand of the clock moves.
00:04
So we know a couple of pieces of information.
00:06
First of all, we know that our s is equal to r times our theta, and we know that in this case, our r radius is how long the minute hand is.
00:13
So we know that r is equal to six inches.
00:21
Now, we know that our theta varies because we want us to find it, how far the minute hand moves in 15 minutes, and how far moves in 25 minutes.
00:28
So we can think of this as two separate problems.
00:30
So we have 15 minutes and 25 minutes.
00:36
And so 15 minutes, we know that, let's see, it has 15 over 60 of the circle, which means one -fourth of the circle...
