Physics word problem! HELP!?
When the 10 km/hr bikes are 20 km apart, a bee begins flying from one wheel to the other at a steady speed of 30 km/hr. When it gets to the wheel it abruptly turns around and flies back to touch the first wheel, then turns around and keeps repeating the back-and-forth trip until the bikes meet, and squish!
How many kilometers did the bee travel in its total back-and forth trips?

Why do teachers post tired old problems? This one was aged when I was in school over half a century ago.
The bikes are 20 km apart and closing the gap at 20 km/hr.
The bee flies at 30 km/hr. Forget *where* the bee flies; for all we care, it could be flying from the nearest McDonald's to your grandmother's house. The important question is this:
In the time it takes the bikes to meet, how far does the bee fly?
