This is an RTD problem. Here is a table based on the given information
\n" ); document.write( "travel . . . . . . . . . .rate . . . . . . . . . time . . . . . . . . . . distance
\n" ); document.write( "walk . . . . . . . . . . .4 . . . . . . . . . . 2.75. . . . . . . . . . . .11
\n" ); document.write( "bike . . . . . . . . . . .16.5 . . . . . . . . . . . . . . . . . . . . . . . .11
\n" ); document.write( "totals . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
\n" ); document.write( "step 1 - we had to find the distance as 4 x 2.75 = 11
\n" ); document.write( "step 2 - find the bike time
\n" ); document.write( "Bike: rate x time = distance
\n" ); document.write( "16.5 x t = 11
\n" ); document.write( "dividing, we get
\n" ); document.write( " t = 2/3 hour
\n" ); document.write( "this is 40 minutes
\n" ); document.write( "
\n" );
