- 13. There is a section of uphill and a section of level road from a to B. if the uphill is 3km per hour, the level road is 4km per hour, and the downhill is 5km per hour, then it takes 54 minutes to go from a to B and 42 minutes to go from B to A. what is the total distance from a to B? I think the answer is: 54 minutes = 0.9 hours, 42 minutes = 0.7 hours, the time for leveling is x hours.
