Question 134324
If the sector goes around the circle 5 times, the leading edge
will be {{{5*75 - 360 = 15}}} degrees ahead of where it started
With this position as a starting point, if the sector goes around 
the circle 5 more times, the leading edge will now be 30 degrees
ahead of it's starting point.
{{{24*15 = 360}}}, so the sector needs to go around the circle 
{{{24*5 = 120}}} times to end up back where it started
