\n" ); document.write( "Assuming you can walk at 4 mph 0r (1/15)mpm and run at 8 mph 0r (2/15)mpm
\n" ); document.write( "Let \"highlight_green%28x%29\" represent how much time can you afford to walk
\n" ); document.write( "D = rt
\n" ); document.write( "Question states: you are one mile from the station
\n" ); document.write( "\"%281%2F15%29mpm%2Ax+%2B+%282%2F15%29mpm%2A%2811-x%29+=+1mi\" ||Multiplying thru by 15 so as all denominators = 1
\n" ); document.write( "\"%281%29mpm%2Ax+%2B+%282%29mpm%2A%2811-x%29+=+15mi\"
