Let distance at reduced speed (10 mph) be D
\n" );
document.write( "Then distance traveled at 60 mph = 210 – D
\n" );
document.write( "Time traveled at 10 mph: 
\n" );
document.write( "Time traveled at 60 mph: 
\n" );
document.write( "We then get: 
\n" );
document.write( "6D + 210 – D = 360 --------- Multiplying by LCD, 60
\n" );
document.write( "6D – D = 360 – 210
\n" );
document.write( "5D = 150
\n" );
document.write( "D, or distance covered at reduced speed (10 mph) = , or  miles \n" );
document.write( "

\n" );
