Answer:

198 km

Explanation:

Eliana drove her car 81 km and used 9 liters of fuel.

She wants to know how many kilometers x she can drive on 22 liters of fuel.

Thus,

81 km - 9 liters

x km - 22 liters

Write a proportion:


(81)/(x)=(9)/(22)

Cross multiply


81\cdot 22=9x\\ \\9x=1,782\\ \\x=198\ km
