NORDIC WALKING
PT.20


As part of his daily exercise, Patrick takes a walk a fixed course. He generally does so at the same speed. On a day that he's feeling energetic, he walks 2 km/hr faster than normal, and found that it took half the usual time plus 15 minutes to finish the course. On a day that he's feeling lethargic, he walks 1 km/hr slower than normal, and found that it takes 30 minutes more than the normal time. What is the distance (in km) of the course that he walks everyday?
