\n" ); document.write( "Some time ago, you asked the following problem:\r
\n" ); document.write( "\n" ); document.write( "``Oscar finished the 44 km trip in 6 hours. He traveled part of the distance at 4km/h and part at 9 km/h. How long did he travel at 9 km/h?\r
\n" ); document.write( "\n" ); document.write( "A. 2 hours\r
\n" ); document.write( "\n" ); document.write( "B. 4.9 hours\r
\n" ); document.write( "\n" ); document.write( "C. 5 hours\r
\n" ); document.write( "\n" ); document.write( "D. 4 hours
\n" ); document.write( "
Let time taken on 9 km/h-leg, be T
\n" ); document.write( "Then we get the following DISTANCE equation: 9T + 4(6 - T) = 44
\n" ); document.write( "Solve for T, the time taken on the 9 km/h-leg.
\n" ); document.write( "It's that simple.....nothing complex! \n" ); document.write( "
\n" );
