Dennis wants to walk 1 mile for exercise each day. He made a table to show the distance from his home to each of 4 different places. What is the total distance from home to the post office and back
home, and from home to the store and back home? If Dennis walks this fatal distance, will he walk
1 mile?

Can someone answer it, and plot it, for 20 points and brainliest answer? p.s. they're the same ! : )
