Homework Statement
The minute hand of a clock travels 6.28 inches in 15 minutes. Find the length of the minute hand. Approximate to the nearest inch, if necessary.
The Attempt at a Solution
I figured the arc length to be [itex]\frac{\pi}{2}[/itex] because it's traveled one quarter of the way around the clock.
I set the equation up like this-
[tex]\frac{\pi/2}{15}x=6.28[/tex]
Then I solve for x by multiplying by the reciprocal, and I'm getting 59.97.
This was a question on a test I had earlier today, and when I did it then, I got approximately 15.001 or something like that. That answer didn't seem right to me, and the answer I'm getting now doesn't seem anymore right. I can't remember exactly how I set it up. What am I doing wrong? The rest of the test was simple, this was the only one that threw me off.
