Agroup of campers uses a map of a state park to plan their trip to and from the campsite. the map looks like a grid in which each unit represents one kilometer. their starting point is located at (4,5) and their campsite is located at (2,8). on the way to the site, the campers will travel due west and then due north. the campers will travel in a straight line back to their starting point on the way back. about how many kilometers will the campers hike all together?

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

its 50 miles away from the starting point
