The question is..
An electron involved in energy conversion in photosynthesis travels about 100 micro meters in 3.0 milliseconds. what is the average speed of the electron in m/s. (metres per second).
and then convert the answer to km/h.
I got 0.33m/s and 1.2km/h.
Is this right? can someone varify for me?
I used to formula v=d/t
v=speed
d=distance
t=time

well i did it again and got the same as before, so i guess my conversions are off. heres my reasoning, please correct me if im wrong:
1cm = 0.01m
1dm= 0.001m
1mm= 0.0001m
1microm= 0.00001m
is that wrong?
and then 0.001ms= 1 s

Mm, I get 0.033 m/s and 0.12 km/h.
Micrometer = 10^ -6 meter
Millisecond = 0.001 seconds
*Edit - Whoops, thanks sojsail.

I get the same as David M. But I disagree with what he said "Micrometer = 12^-6 meter". Probably just a typo but you don't need the confusion just now. 1 Micrometer = 1x10^-6 meter
