look this up on mathowl on the app store and there is ur answer
The minute hand has swept through 46 minutes on the clock. You have to set up a ratio to solve this:

You can compare the 60 minutes on a clock to 360 degrees because 60 minutes on a clock is one whole rotation. So then, you cross multiply and simplify:

Therefore, the minute hand has swept through an angle with a measure of 276 degrees.
So "of" means multiply and 30% is .3 so multiply .3 by the 240 times and u get... 72!
