One car is moving at a speed of 100 mph and the other is moving at 70 mph. Assuming that the cars start moving at the same time how long does it take for the two cars to meet? Solution Let’s let t represent the amount of time that the cars are traveling before they meet. Now, we need to sketch a figure for this one. This figure will help us to write down the equation that we’ll need to solve. From this figure we can see that the Distance Car A travels plus the Distance Car B travels must equal the total distance separating the two cars, 500 miles. © 2007 Paul Dawkins 74 http://tutorial.math.lamar.edu/terms.aspx College Algebra Here is the word equation for this problem in two separate forms. æ Distance ö æ Distance ö ç ÷+ç ÷ = 500 è of Car A ø è of Car B ø æ Rate of ö æ Time of ö æ Rate of öæ Time of ö ç ÷ç ÷+ç ÷ç ÷ = 500 è Car A ø è Car A ø è Car B ...
