Hello, I've been having difficulty with this problem and I need some help on how to start and solve this question:
Bruce bicycles across a Bridge, ride a flat road, then up a hill. At the top, he turns around and goes back down the
hill, over the flats, and back over the bridge. As Bruce looks at his speedometer,
he sees that he goes a steady 15 miles per hour (mph) on the flats (including the
bridge), 6 mph up-hill, and 24 mph down-hill. It turns out that the entire ride takes an hour and a half, and that he has
traveled 18 miles.
a. How many “flat” miles were in Bruce's ride? How many up-hill miles?
How many down-hill miles?
Let me know if you can help!
