150 km uphill and 500 km downhill..
As let the car goes uphill for time t ..and downhill for 15 - t time ...so distance covered during uphill motion is 30t and downhill motion is (15-t)50 ...
30t + (15-t)50 = 650
t=5 hrs
Distance during uphill motion = 5×30= 150 km ..
Distance ( downhill) = 650-150=500km
