Question 790517: Two trains 130 miles apart are traveling toward each other along the same track. The first train goes 50 miles per hour; the second train rushes along at 80 miles per hour. A fly is hovering just above the nose of the first train. It buzzes from the first train to the second train, turns around immediately, flies back to the first train, and turns around again. It goes on flying back and forth between the two trains until they collide. If the fly's speed is 120 miles per hour, how far will it travel? Answer by solver91311(24713) (Show Source):
The two trains are approaching each other at 50 plus 80 = 130 miles per hour. Since they are 130 miles apart, they will meet in one hour. If the fly is going 120 miles per hour, he will travel 120 miles in that hour.
