A microbiologist measures the speed of a swimming bacterium. The 2bacterium covers a distance of 6.82 microns in 3.5 seconds. The biologist wished to compare the speed of the bacteria with other animals, but the
speeds of other animals are listed in kilometers per hour. What is the speed of the bacterium in kilometers per
hour? (1 micron 1x 10-6 m) Use scientific notation and express your answer to the correct number

answer: the correct answer id option(d).

explanation:
