Section 3-6

In class we just competed section 3-6. One thing we learned was how to define a variable in terms of another. To solve this problem you have to decide which unknown quantity the variable will represent. Then you have to show the other quantity in terms of that variable. Another thing we learned is dealing with consecutive integers. First you have to define a variable before describing the equation in words. Make a variable the first unknown integer and then define the other numbers in terms of that first unknown integer. Last but not least we learned how to solve problems with same direction travel, opposite direction travel, and round trip travel. The first step is to define the missing variables in the problem. Then you have to create a table to relate the numbers that includes rate time and distance because rate times the time equals the distance. You then write out and solve the equation to get your final answer.
