摘要

This one generated a great deal of interest; there are many mathematical minds out there, that's for sure.We actually gave you two problems: First, we had a train, traveling 60 mph, following a course that is 78 miles in length, ending at our offices. At the same time the train left its departure point, a bird left our offices (we trained her well) and flew to meet the train. We have a fast bird who can fly 70 mph.
