Hello,
\n" ); document.write( "First let's find how much grass there is to cut by subtracting 1290 from 1600.
\n" ); document.write( "That gives us 310 sq ft.
\n" ); document.write( "Now divide 2 sq ft per minute into 310 sq ft. to give us:
\n" ); document.write( "155 seconds
\n" ); document.write( "Now if the yard is 1600 st then it would take:
\n" ); document.write( "800 seconds or 13 1/3 minutes.
\n" ); document.write( "The problem isn't totally clear what is to be cut.
