You can put this solution on YOUR website! at 10am a plane leaves Boston,Massachusetts, for Seatle,Washington, a distance of 3000mi.One hour later a plane leaves Seatle for Boston. Both planes are traveling at a speed of 5000mph.How many hours after the plane leaves Seatle with the planes pass each other?
-------------------
They travel 3000 miles at 10000 miles/hr
3000/10000 = 0.3 hours
-----------------
Those are fast planes.
