WHO KNOWS THEIR FREEWAYS??? my homework.HELP!?

If you go to the Yahoo home page (www.yahoo.com), click on maps on the left side, and it will pull up a site that allows you to plug in the cities. In other words, it will ask you where are you starting out, and where do you want to go. Just put the names of the cities in and in no time, it will give you the route you need to travel. All interstates that run east to west are even numbers (I-80) and those that run north to south are odd (I-5). Good luck with graduating.
