Answer:
<em>To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.</em>
Step-by-step explanation:
<u>Proportions</u>
The hybrid car can travel 40 miles per gallon.
Since one mile is equivalent to 1.6 Km, the distance traveled per gallon is 40*1.6 = 64 Km.
Now the distance is expressed in Km, we can find the gallons needed to travel 20 Km, by calculating 20/64 = 0.3125.
To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.
