In this problem, the three bugs start at the corners of an equilateral triangle (with side length=10 inches).
Again, the bugs travel directly towards their neighbor (counter-clockwise). And, again, each bug homes in on its target, regardless of its target's motion. So, their paths will be curves spiraling toward the center of the triangle, where they will meet.
What distance will the bugs have covered by then, and how did you determine it?
(In reply to re(3): There must be some bugs in this solution !!!
SK: "BTW, Penny, you updated your answer (below) with '20' but that's not quite right either...."
But I did make it clear that it was updated, that it was wrong originally... Isn't 20 inches per bug (60 total) the right answer? 20 (total) was Charlie's answer, and you don't seem to be picking on him. I guess you prefer to fight with girls. Anyway, that calculator of mine was a free Internet download, and it's been worth every cent!!
