Anu and Eby went on a hiking trip that was 36 km. Amy's backpack weighed 7kg and Eby's backpack 8kg. They hiked 9km the 1st day and 6km the 2nd day. If they hiked equal number of km the next 3 days, how many km a day did they hike on these days?

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
