combined speed = 420 + 413.333 = 833.333
\n" ); document.write( "---
\n" ); document.write( "s = d/t
\n" ); document.write( "833.333 = 2000/t
\n" ); document.write( "t = 2000/833.333
\n" ); document.write( "t = 2.4 hours
\n" ); document.write( "t = 2 hours and (60 * 0.4) minutes
\n" ); document.write( "t = 2 hours and 24 minutes
