Traveling 90 mph, it takes the Express Train six seconds for the entire train to enter a two-mile tunnel.
\n" ); document.write( " How many seconds will it take the Express to completely travel through this tunnel?
\n" ); document.write( ":
\n" ); document.write( "find the length of the train: 6\"90%2F3600\"* .15 mi long
\n" ); document.write( ":
\n" ); document.write( "Time = dist/speed
\n" ); document.write( "Length of the train added to the tunnel dist: 2.15 mi
\n" ); document.write( ":
\n" ); document.write( "t = \"2.15%2F90\"*3600
\n" ); document.write( "t = 86 seconds
