if the truck travels at 55 miles per hour for 1 hour, then the truck has traveled 55 miles.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "55 miles * 5280 feet per mile * 12 inches per foot = 3484800 inches.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the radius of the wheel is 14 inches, then the circumference of the wheel is 2 * pi * 14 inches.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3484800 / (2 * pi * 14) = 39615.93898 rotations of the tire.\r
