On a graph with a horizontal axis labeled x $($m$),$ a path begins at x $=2.$ The path then continues to the right to x $=10,$ then curves back to the left to x $=8,$ then curves to the right again, ending at an arrowhead at approximately x $=11.$ 

Find:

 $($a$)$ 

 

the total distance traveled

 

 

 $($b$)$ 

 

the displacement from start to finish
