For many years, the number of sharks in Pelican Bay has been twice the number of Pelicans in Shark Bite Cove.   But today scientists say one-third of the Pelicans in Shark Bite Cove have moved to Pelican Bay.  If there are still 60 sharks in Pelican Bay,  how many Pelicans remain in Shark Bite Cove?
If there are 60 sharks in Pelican Bay, and this number is twice the number of Pelicans that usually live in Shark Bite Cove, then there were 60/2=<<60/2=30>>30 Pelicans in Shark Bite Cove.
If one-third of the Pelicans in Shark Bite Cove move to Pelican Bay,
then 30/3=<<30/3=10>>10 Pelicans will have moved away.
This would leave 30-10=<<30-10=20>>20 Pelican remaining in Shark Bite Cove.
