###Human: 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?, ### Assistant: 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=30 Pelicans in Shark Bite Cove.
If one-third of the Pelicans in Shark Bite Cove move to Pelican Bay,
then 30/3=10 Pelicans will have moved away.
This would leave 30-10=20 Pelican remaining in Shark Bite Cove. 
 So the answer is :  20
