Answer: 7km

Step-by-step explanation:

Hi, to answer this question, first we have to add the kilometers hiked in the first 2 days.

9km+6km = 15km

Since the trip was 36km, we have to subtract 15 to 36:

36-15 = 21 km left

Since they hiked an equal number of km the next 3 days, we have to divide the remaining km by 3:

21/3 = 7km
