Question

A car manufacturer states that a particular car

* uses 5 liters of fuel in travelling 100 km,
* produces 110 grams of CO2 for each kilometer travelled.
The mass of CO2 produced by one litre of fuel is:

Answer 1

The mass of CO2 produced by one liter of fuel is 2,200 gr/lt

Explanation:

Proportions

To find the cross-relation between the mass of CO3 produced and the liters of fuel used we must find the unit rate of both relationships given.

We know:

The car uses 5 liters of fuel per 100 Km. The unit rate is 5/100 lt/km

The car produced 110 grams of CO2 for each kilometer traveled. The unit rate is 110 gr/Km

Since the kilometers is the common unit, we find the unit rate of CO2/fuel:

`\displaystyle ((110)/(1))/((5)/(100))=(110)/(1)}*(100)/(5)}= 110*20 = 2,200`

The mass of CO2 produced by one liter of fuel is 2,200 gr/lt
