A microbiologist measures the speed of a swimming bacterium. The bacterium covers a distance of 2.16 microns in 5.0 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 = 1 x 10–6 m) Use scientific notation and express your answer to the correct number of significant figures.

**Graham**, Friday, September 27, 2013 at 10:59amYou simply need to express 2.16 micrometres in 5.0 seconds as some kilometres per hour, retaining the appropriate number of significant figures during conversion.

1 μm = 1×10^–6 m

1 km = 1×10^+3 m

1 hr = 3600 s

2.15μm / 5.0s = _._ ×10^__ km/hr
