The problem is to convert $85650 \text{ mm}$ to kilometers ($\text{km}$).

1. Problem Description

The problem is to convert $85650 \text{ mm}$ to kilometers ($\text{km}$).

2. Solution Steps

We need to convert millimeters to kilometers.

First, we convert millimeters (mm) to meters (m).

There are 1000 mm in 1 m.

So, $1 \text{ mm} = \frac{1}{1000} \text{ m}$.

$85650 \text{ mm} = 85650 \times \frac{1}{1000} \text{ m} = 85.65 \text{ m}$

Next, we convert meters (m) to kilometers (km).

There are 1000 m in 1 km.

So, $1 \text{ m} = \frac{1}{1000} \text{ km}$.

$85.65 \text{ m} = 85.65 \times \frac{1}{1000} \text{ km} = 0.08565 \text{ km}$

3. Final Answer

$0.08565 \text{ km}$
