Ascent and descent

Car goes 114 km track, which consists of ascent and descent at time of 1 hour 35 minutes. When climbing moves at the speed 48 km/h and downhill 25 m/s. What is the length of climb and descent?

Result

a =  32.571 km
b =  81.429 km

Solution:


a+b=114
a/48 +b / (25*3.6) = 1+35/60

a+b = 114
5a+2.666667b = 380

a = 2287 ≈ 32.571429
b = 5707 ≈ 81.428571
