Work your way through this:
1) If a train leaves Boston at 8 AM going 40 kilometers per hour, going East and a train leaving Portland Oregon leaves at 10 AM going West on the same track going 25 miles per hour and a bald eagle is flying back and forth between the planes at 30 miles an hour, how many kilometers has the eagle flown by the time the two trains collide?
2) Based on your answer from 1) above, an eagle drops 1 feather every 9.63 hours, how many feathers did he lose?
3) Oh we forgot to tell you, the eagle flies slower for each feather he loses. You have to start over.
