Answer:

97.8 liters

Step-by-step explanation:

We use proportions:

If 7.4 liters are needed for 100 km, then we can write the rate:

7.4 L / 100 km  which should equal the rate for the x number of liters needed for a 1322 km trip:

7.4 L / 100 km = x / 1322 km

solving for "x" by multiplying both sides by 1322:

x = 97.828 liters

which we may be able to round to 97.8 liters
