Step-by-step explanation:
I don't know if you do this the same way I did, but..
The first step is to subtract 9 on both sides, like this.
13w + 9 = 178
        -9    -9
 You'll end up with:
13w = 169
I don't know if you need the answer or not but I'll help you out. 
For the second step, divide both sides by 13w.
13w = 169
/13w   /13w
  w = 13
Hope this helped!

Using the numbers stated in the problem
0.37m/ft * 5180ft/mile * 15mile * 1km/1000m = 28.749 km
