The Attempt at a Solution

i really can't attempt it because i have no idea what to do, i forgot how to do this stuff

Why don't you look up what a micron is first? Then km as well. And figure out how many of one is in the other?

I'm starting to have problems taking you seriously.

 

[afcwestwarrior]

one micron equals 10^-6 meters and 1 km equal 10^3 meters

 

[afcwestwarrior]

10^9 microns equal 1 km

1,000m/1km * 1 micro u/1*10^-6=10^9

 

[afcwestwarrior]

It equal 10^9 or 1,000,000,000

 

[Dick]

10^9 microns equal 1 km

1,000m/1km * 1 micro u/1*10^-6=10^9

Sure thing. That wasn't so hard, was it?

No it wasn't. I'm very rusty on my physics and Calculus.

Practice makes perfect. You might try finding a book with solutions and practicing offline. I don't think all of these problems need posting.
