No clear distance is given, just "up" and "down" the hill. This is some number of units. I'm picking h as this unknown distance for the hill.

Which way__________rate units/min____________time_____________distance
UP___________________8_______________________h/8______________h
DOWN_________________8*60___________________h/(8*60)__________h

Total Distance = 2h
Total Time minutes =

Overall rate =
=
= units per minute.
