 Okay, this will be the last of these fuel economy problems we do for the night. This one we're converting kilometers per liter to miles per gallon. So just like the last one, we need the two conversion factors. One kilometer equals 0.621 miles, and one gallon equals 3.785 liters. And you just start with that initial fuel economy rating, 12.8 kilometers per liter. And you want it in miles per gallon, so first we're just going to cancel out the kilometers to get miles. So now our units are miles per liter, but we don't want that. We want it in miles per gallon. So we use the other conversion factor, putting liters on top, so we can cancel those out and get miles per gallon. And then we just go ahead and multiply across the 12.8 times 0.621 times 3.785, and that's going to give us an answer to three sig figs, because that's how many was given in the problem at 30.1 miles per gallon. Okay, so hopefully that makes sense. Let me know if you have any issues.
