Step-by-step explanation:
You want to know the cost per gallon of gas and the cost for 12 gallons of gas when the cost per liter is $1.31 CDN and the exchange rate is $1.02 USD per CAD.
<h3>Cost per gallon</h3>
The conversion between liters and gallons is ...
1 US gallon = 3.785411784 liters (exactly)
Then the cost conversion is ...
![\dfrac{\$1.31\text{ CAD}}{1\text{ L}}\times\dfrac{3.785411784\text{ L}}{1\text{ gal}}\times\dfrac{\$1.02\text{ USD}}{\$1.00\text{ CAD}}\approx\boxed{\$5.058\text{ USD/gal}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5C%241.31%5Ctext%7B%20CAD%7D%7D%7B1%5Ctext%7B%20L%7D%7D%5Ctimes%5Cdfrac%7B3.785411784%5Ctext%7B%20L%7D%7D%7B1%5Ctext%7B%20gal%7D%7D%5Ctimes%5Cdfrac%7B%5C%241.02%5Ctext%7B%20USD%7D%7D%7B%5C%241.00%5Ctext%7B%20CAD%7D%7D%5Capprox%5Cboxed%7B%5C%245.058%5Ctext%7B%20USD%2Fgal%7D%7D)
The cost per gallon in terms of US dollars is about $5.06.
<h3>Cost per tank</h3>
The cost for 12 gallons will be ...
(12 gal)×($5.058 /gal) ≈ $60.70
It will cost you $60.70 to fill your 12 gallon tank.

<em>Additional comment</em>
The price of gas is routinely specified to tenths of a cent, both in the US and in Canada. As of today, the cost of gas in Canada has declined to $1.864 CAD/liter. At today's exchange rate of about $0.77 USD per CAD, the equivalent price is $5.406 USD/gal.
So, the question is telling you that you jog one hour a day (equal to 5.5 miles) and you do it threw times a week.
5.5 miles * 3 times = 16.5 miles
So each week you will jog 16.5 miles.
Have a nice day :D
See could have got the correct answer because if there was more numbers in the decimal you can round it to get .34 or because both answers have 12.3 and it doesnt matter about the other numbers after 3
