The hike to the campsite is 4 kilometers long. If we each take turns carrying the tent got 4 fifth of a kilometer, how many times will the tent change hands?

4/5 kilometre = 0.8 km

If the hike is 4km in total, then the number of times the tent would be swapped is:

(4/0.8) - 1

= 5 - 1

= 4 times (5 is the number of sections of 0.8 km in the 4 km hike however since one person already started with the tent in the first section it would need to be swapped between the two people 4 times - hopefully that makes sense)
