\n" ); document.write( " At the end of the trip. How many miles will each tire have been used?
\n" ); document.write( ":
\n" ); document.write( "I am going to say 3/5 * 1000 = 600 mi per tire, or 3000 tire-miles divided by 5,
\n" ); document.write( "also gives 600 mi per tire.:
\n" ); document.write( "To rotate the tires:
\n" ); document.write( "replace tire 1 with tire 4 after 400 mi, tire 1 has 200 mi left on it
\n" ); document.write( "replace tire 2 with tire 5 after 400 mi, tire 2 has 200 mi left on it
\n" ); document.write( "replace tire 3 with tire 1 after 600 mi, at 800 mi replace tire 1 with tire 2 \n" ); document.write( "
