Answer:
198 km
Step-by-step 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:
[tex]\dfrac{81}{x}=\dfrac{9}{22}[/tex]
Cross multiply
[tex]81\cdot 22=9x\\ \\9x=1,782\\ \\x=198\ km[/tex]
