Math Problem		Climbing Snail		  Name ________________________

A snail climbs a castor plant at a rate of two cm/hr.  After three hours, it 
rests for two hours.  While the snail rests, it slides back one cm/hr.  The 
castor plant is two meters tall when the snail starts to climb and grows at a 
rate of nine cm/day (Only the upper end of the plant grows longer).  How long 
will it take the snail to reach the top of the plant?  Will the snail ever 
reach the top of the plant?  If the snail does reach the top, how tall will the 
plant be at that time?
