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.

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
