You can put this solution on YOUR website!
d = r*t is the fundamental distance equation.
\n" ); document.write( ".
\n" ); document.write( "you need to know 2 of these to calculate the 3rd.
\n" ); document.write( ".
\n" ); document.write( "3 mph = r
\n" ); document.write( "2 mph = r
\n" ); document.write( ".
\n" ); document.write( "but unless you know 'd', you cannot calculate 't'
\n" ); document.write( ".
\n" ); document.write( "Say d = 9
\n" ); document.write( ".
\n" ); document.write( "9 = 3t
\n" ); document.write( "t = 9/3 = 3 hr : It takes 3 hr at 3 mph to go 9 miles
\n" ); document.write( ".
\n" ); document.write( "9 = 2t
\n" ); document.write( "t = 9/2 = 4 1/2 : It takes 4 1/2 hr at 2 mph to go 9 miles.
\n" ); document.write( ".
\n" ); document.write( "And so forth.
\n" ); document.write( " \n" ); document.write( "
