    Story problem

    okay I have a story problem that goes like this Nella drove from Albuquerque, New Mexico, to the Garden of the Gods rock formation in Colorado Springs. It took her six hours to travel 312 miles over the mountain road. She came home on the highway. On the highway it took five hours to travel 320 miles. How fast did she travel using the mountain route? How much faster (in miles per hour) did she travel using the highway route? Not sure how to set the problem up?

    The units give you a hint. "per" means "divided by". Miles per hour = miles divided by hours...

    By the way these are average speeds we are dealing with. Average speed = total distance / total time.
