Answer:
13 trips
Explanation:
Zane has already walked 15 kilometer this week, plus he plans to walk 2 kilometers during each trip to school. How many trips will Zane have to make in all to walk a total of 41 kilometers?
Let the number of trips = x
This is solved as:
41 = 15 + 2x
41 - 15 = 2x
26 = 2x
x = 26/2
x = 13
Therefore, Zane will have make 13 trips in all to walk a total of 41 kilometers
