Question

A car travels 55 mi/gallon of gasoline. How many km/L will it go?

Answer 1

21 km/L

Explanation:

1 m = 1.6 km
1 qt = 1.06 L
4 qt = 1 gal

`(55 mi)/(1 gal)` * `(1.6 km)/(1mi)` * `(1 gal)/(4 qt)` * `(1qt)/(1.06L)`

((55mi/gal * 1.6km) ÷ 4qt)) ÷ 1.06L

21km/L

(The formulating is a bit off)
