Bacteria move back and forth by using their flagella (structures that look like little tails). A bacteria moves with 50 μm/s have been observed to –X direction for 2.3 second, and it move forth to the +x direction for 30 μm/s within 1 seconds.
a) What is its total displacement?
b) What is the total distance ?
c) Find his average velocity for his whole movement?
