Charlie heard that adding salt to water changes the amount of time it takes water to boil, and he wanted to find out if adding sugar to water would change the time it takes water to boil.

First, he boiled a pot of water with no sugar. Then he boiled the same amount of water with 1 tablespoon of sugar, and then with 2 tablespoons of sugar. The graph below shows the results of Charlie's experiment.

Based on Charlie's data, how long can he predict it will take the pot of water to boil if he puts 1.5 tablespoons of sugar into the pot?
