Two trains, 1200 miles apart, are traveling toward each other on the same track. One travels at 70 mph while the other travels at 130 mph. "Superfly" Sarah, perched
on the front of the slower train, flies toward the faster train at 240 mph . When she reaches the front of the faster train, she instantly turns around and flies back toward the
slower train, again at 240 mph . This continues until the two trains crash and smash poor Sarah. What is the total distance in miles that Sarah travels before her untimely demise?
