Goal: 13-3/5 cm
\n" ); document.write( "Present: 8 cm
\n" ); document.write( "difference: (13-3/5)-(8)= 5-3/5 cm =5.6cm-------> this is the one the plant need to attain at a rate of 4/5 = 0.8 cm per week.
\n" ); document.write( "= \"5.6cm%2F%280.8cm+%2Fweek%29\"
\n" ); document.write( "=\"7+weeks\"
\n" ); document.write( "In 7 weeks the plant reaches 13-3/5 cm, plus 1 more week= 4/5+(13-3/5)=14-2/5 cm
\n" ); document.write( "After \"8+weeks\" it exceeded the height 13-3/5 cm.
