Chlamydomonas, algae known as green yeast, is a popular organism for lab study. These cells move through their watery environment by waving a pair of flagella. Normally the flagella wave in synchrony, moving the cell smoothly. However, some individuals only have a single flagellum, and its asymmetric wave causes the cell body to rotate as it moves. If one particular cell rotates its body 4 times in 0.3 seconds, how many rotations/revolutions does the cell complete in 20 seconds?
