move back and forth by using their flagella (structures that look like little tails). Speeds of up to 50 ?m/s (50×10?6 m/s) have been observed. The total distance traveled by a bacterium is large for its size, while its displacement is small. Why is this?

Step-by-step solution Step 1 of 2 Bacteria move with speeds of up to so the total distance traveled by bacterium is large. But Bacteria move back and forth, so the resultant displacement which is the difference of initial point and final point is very less compare to the total distance traveled.
