*** As you can already see, it’s probably helpful when solving word problems to first write an equation in words before you write it in mathematical symbols!!!! *** This word equation is called a verbal model. The verbal model is then used to write a mathematical statement, which is called an algebraic model.

The Bullet Train runs between the Japanese cities of Osaka and Fukoka, a distance of 550 km. When it makes no stops, it takes 2 hours and 15 minutes to make the trip. What is the average speed of the Bullet Train? Use your charts on pg 28 to get your formulas. Figure out what you’re trying to find and work from there!!!!!!!!! D=rt

You own a lawn care service. You want to know how much money you spend on gas to travel to out-of-town clients. In a typical week you drive 600 miles and use 40 gallons of gas. Gas costs $1.25 per gallon, and your truck’s fuel efficiency is 21 miles per gallon on the hwy and 13 miles per gallon in town.
