does water or saltwater boil faster
 
We did this experiment with cold water and cold saltwater 3 trials each and had the results come back that the salt water boils faster almost 50 seconds sooner than the water. I thought that was correct, but according to information on the encyclepedia, that is not true. Can you help?
