Very close, but could be a bit better :) how did you do it?

did you say the minute hand has 14 cm. long

so i place the clock at 11:00 then i rotate the minute hand thru 11:15 and i took measurement from one point to another and my result was 20 cm.

so if a was wrong i hope someone can do it better.

thanks

ah I see it was close so i got curious :) it should be 22 if calculated!

Thanks!
