Mathematical Reflection 4
__Big Idea: __ Observations and descriptions of changes in the world around us are the first steps in discovering and learning about patterns

Q. 1) The Larson family is traveling from Michigan to Florida at an average speed 60 miles per hour. Write and equation for a rule you can use to calculate the distance they traveled for any given no. of hours.

Ans. 1) The equation is //**d=60t **//

Q. 2) What are the advantages of having an equation to represent the Larson family's situation? What are the advantages of having a table? A graph?

Ans. 2) The advantages of having an equation is that you can quickly look at the rule and know what to do. The advantage of a table is that you know the exact numbers. The advantage for a graph is that you can determine what speed they're at easily by looking at how close or far the points are.

__Summary: __In this investigation I learned what rules and equations are & how to make your own rule & equation for problems and relate them to real life. These equations are very helpful because you can calculate things for any time quickly.
