Cosmolgy- Density of the Universe

[EP]

Assume the universe has an average galaxy density of p=0.9 Mpc^-3. Each galaxy has a diameter of 30 kpc. How far would you see on average in any direction before your line of sight would hit a galaxy? Assume a Eucledian spcae and infinitely large and infinitely old universe.

Help get me started.
Thanks

My guess is the answer is that no matter where you look you'll see a galaxy under these conditions.

What units are are kpc and mpc?
