Answer 1

the answer is b because is basically just gave you the answer in the question

Answer 2

Answer: B 0.002 meters per second

Step-by-step explanation:

Given : Small earthworms travel at speeds of about 0.2 centimeters per second.

We know that 1 meter = 100 centimeters

Then, 1 centimeter = $\dfrac{1}{100}$ meters

Now by using UNITARY METHOD,

0.2 centimeters per second.= $0.2\times\dfrac{1}{100}$meters per second

=0.002 meters per second

Hence, B is the correct option.
