Two trains are heading towards each other on a linear track. One train travels at a speed of 60 miles per hour, and the other at 50 miles per hour. A fly starting at one train travels back and forth at a speed of 100 miles per hour. If the trains start 100 miles away from each other, how far will the fly travel before it is squashed by the collision?
\n" ); document.write( "-----------------------
\n" ); document.write( "The trains approach each other at 110 mph (50 + 60)
\n" ); document.write( "It takes the trains 100/110 hours to meet.
\n" ); document.write( "The fly flies at 100 mph for 100/110 hours.
\n" ); document.write( "The fly's distance = 100*(100/110) miles
\n" ); document.write( "d =~ 90.91 miles \n" ); document.write( "

\n" );
