document.write( "If you note that the ratio of the two speeds is 2:3, then finding the answer is easy with a bit of mental arithmetic.<br><BR>\n" );
document.write( "Since the ratio of 38mph to 57mph is 2:3, the ratio of times at the two speeds (since the distances are the same) has to be 3:2.  Since the total time was 5 hours, they spent 3 hours driving there at 38mph and 2 hours driving back home at 57mph.<br><BR>\n" );
document.write( "So the distance from their home to the Grand Canyon is 38*3 = 144 miles, or 57*2 = 114 miles. </SPAN>\n" );
