About Formulas Can be thought of as a “recipe” for solving a particular type of problem. A formulas can be used as a model for problems in the areas of geometry, banking and finance and science.

Distance Formula (d)istance=(r)ate(t)ime can use everyday to decide what time to leave/arrive at a place on time (or how fast to drive to get there) Also the formula cops used to use to catch speeders.
