50 miles
I found it here
Its simple. Both bicyclists meet in one hour, since they're going 20 miles per hour and each one travels 20 miles (1/2 of 40 miles). Since the bird is flying 50 miles per hour, in one hour the bird will fly 50 miles.
Two bicyclists start out 40 miles apart and ride toward each other at 20 miles per hour. A bird (swallow) flies 50 miles per hour from one bike to the other, back and forth, starting when the two bicyclists are 40 miles apart. When the bicyclists meet how far did the swallow fly?
