Well there's a simple question with a rather more complex answer.

#### Explanation:

The nearest galaxy is the Andromeda galaxy at about 2.5 million light years. Now it is just a unit conversion problem.

A light year is the distance light travels in a year .... about 6 million, million miles ($5.879 \times {10}^{12}$ miles if you understand that method of writing large numbers.)

So the nearest galaxy is roughly 15 000 000 000 000 000 000 miles ($15 \times {10}^{18}$miles)

A long way, but it will one day engulf our galaxy and shred it to bits. Sleep well ;)
