\n" ); document.write( "How long will it take the car going 70mph to travel 70 miles? 1 hour, right? Your brain mentally did that automatically, dividing \"70miles%2F70mph\"
\n" ); document.write( "For 80mph, do the same thing -- just with the different value
\n" ); document.write( "\"70miles%2F80mph\"=.875 hours
\n" ); document.write( "Multiply the fraction by 60 (60 minutes in an hour) to find that it will take him 52.5 minutes
\n" ); document.write( "
\n" );
