How long before the bug completly circles the 14 feet by 20 feet room. I know the answer is 163.2 minutes or 2.72 hour, the answers are in our book but our teacher wants us to explain and I do not understand how to get those results. I have tried so far 14*20=280/5=56 14*20=280*12=3360/5=672 20*12=240/5=48 14*12=168/5=33.6 5*12=60/20=3 I simply so not understand this problem. \r<BR>\n" );
