What is the magnitude of the bacterium’s average velocity for the entire trip?

The bacterium E. coli is a single-cell organism that lives in the gut of healthy animals, including humans. When grown in a uniform medium in the laboratory, these bacteria swim along zigzag paths at a constant speed of 17 ?m/s . The following figure shows the trajectory of an E. coli as it moves from point A to point E.
