Boiling Point of Solutions

Why does urea and salt water in an experiment I recently took part in reach their boiling points, before the distilled water? Stability in the urea and salt water is reached before it is in the distilled water. Also, I need an explained answer in why the urea and salt solutions' boiling points are higher. Thanks.

We don't know why the solutions boiled before the pure water.

We have several explanations posted about why the boiling point of the solutions is higher than of pure water.
