Joey and Sue are biking on a similar route consisting of different terrains. Joey bikes uphill at 6 kph, downhill at 25 kph, and on flat land at 15 kph. Sue bikes uphill at 12 kph, downhill at 35 kph, and flat at 25 kph. Joey starts from town X to town Y, a 12 km uphill stretch, then goes from Y to Z, which is 10 km downhill, before returning to X via a 20 km flat road. Sue uses the same route but starts from Z heading to Y downhill, then from Y to X (uphill), and finally from X back to Z (flat).
