Pirate Rick sailed his ship to a tropical island in search of a site to bury his treasure.  After finding the perfect site, it took him 4 hours to dig up 8 feet of sand under which to bury the treasure.  Once the treasure was buried, he left the island.  Then, a tropical storm came and washed away half of the sand from on top of the treasure.  Next, a giant tsunami wave poured over the island, adding 2 feet of new sand back onto the site of his treasure. When Pirate Rick returned, how long did it take for him to dig up his treasure?
Pirate Rick digs at a rate of 8 feet of sand per 4 hours, or 8/4=<<8/4=2>>2 feet per hour.
Of the 8 feet of sand that were initially on top of the treasure, the storm washed 8/2=<<8/2=4>>4 feet of sand away.
Thus, after the storm and the tsunami, the treasure was buried beneath 8-4+2=<<8-4+2=6>>6 feet of sand.
Digging at a rate of 2 feet per hour, Pirate Rick could uncover his treasure in 6/2=3 hours.
