Small earthworms travel at speeds of about 0.2 centimeters per second. What is this speed in meters per second?

Question

0.0002 meters per second
0.002 meters per second
20 meters per second
200 meters per second

Answer 1

To convert centimeters to meters, we need to know that 1 centimeter is equal to 0.01 meters. Therefore, to convert 0.2 centimeters per second to meters per second, we use the following calculation:

$$0.2,\text{cm/s}=0.2\times 0.01,\text{m/s}=0.002,\text{m/s}$$

So, the speed of small earthworms in meters per second is 0.002 meters per second.
