Question 869803: Two bicyclists start 100 miles apart and head towards each other, each one going 10mph. At the same instance, a fly leaves the first bike and flies at 20mph to the second. When it gets there, it immediately turns around and heads back to the first. Then it repeats, going back and forth between the two bikers. By the time they reach each other, how far will the fly have travelled?

Two bicyclists start 100 miles apart and head towards each other, each one going 10mph. At the same instance, a fly leaves the first bike and flies at 20mph to the second. When it gets there, it immediately turns around and heads back to the first. Then it repeats, going back and forth between the two bikers. By the time they reach each other, how far will the fly have travelled?
---------
Biker DATA:
Their closing rate is 20 mph.
Time for them to meet is 100 miles/20 mph = 5 hrs
-----
In that time the fly travels 5 hrs*20 mph = 100 miles
