Lesson Summary:

In this lesson, the math problem involves finding the rate of a crew team in still water and the rate of the current. By creating a chart and defining variables for the rates of the crew and current, two linear equations are formed. After simplifying the equations and using the addition method, the rates are found to be 6.5 miles per hour and 2.5 miles per hour, respectively. These rates are then checked against the original problem to ensure the solution is correct.

Lesson Description:

Shows how to solve a word problem involving the rate of a current and rowing in still water using 2 variables and 2 linear equations.
