If a dog runs 25m east and then turns around and runs
back 20 west, what is the total distance ran? How far is the
dog displacement from the starting line?
The dog ran a total distance of 45m but he is only 5m away from the starting line
Explanation: When you add 25 to 20 you get 45 for the total distance and if he ran back in the same direction then you would subtract 20 from 25 and get 5m
