distance = rate * time
\n" ); document.write( "distance + distance = total distance
\n" ); document.write( "rate * time + rate * time = 7
\n" ); document.write( "6(h) + 5(1.3 - h) = 7
\n" ); document.write( "6h + 6.5 - 5h = 7
\n" ); document.write( "h = 0.5
\n" ); document.write( "Plug: 1.3 - h = 1.3 - 0.5 = 0.8
\n" ); document.write( "He ran at six miles an hour for 0.5 hours or 30 minutes.
\n" ); document.write( "He ran at five miles an hour for 0.8 hours or 48 minutes. \n" ); document.write( "
