PLEASE HELP ME

You place a cup of 205°F coffee on a table in a room that is 72°F, and 10
minutes later, it is 195°F. Approximately how long will it be before the coffee
is 180°F? Use Newton's law of cooling:

Every 10 min it goes down 10 degrees.

We need it to go down 205-180=25 degrees.

Since it goes down 1 degree per min, it would take 25 min. I don't know about the law part though.
