Yuan went on a 114km bike ride over a mountain pass.She averaged 24km/hr going up the moutain and 36 km/hr going down the other side.This all happened when Yuan in fantastic shape and could cycle for hours.Once school went back in her cardiovascular fitness deteriorated and she gave up cycling until the following summer.If the time spent going down was one hour less,find how many kilometers were traveled in the uphill part of the ride.

设上坡距离为 x,下坡用时为 y,则上坡用时为（y+1）,根据给出的条件列方程：
1) x/(y+1) = 24
2) (114-x)/y = 36
解方程得出：x = 60,y = 1.5
因此,上坡距离为 60 公里（60 kilometers were traveled in the uphill part of the ride）
