I am having difficulty figuring out how to set up the following problem, though I have no problem in executing the steps to actually solve. Here's the word problem: Los Angeles and San Francisco are about 360 miles apart. You travel north to San Francisco on a Thursday morning, experiencing little traffic. However, your return trip on a Sunday afternoon, you encounter heavy traffic and travel at an average rate of 20 mph less than on your way up. Your return trip takes 3 hours longer than your trip north. How fast are were you going in each direction on average?
