1.53 gallons of fuel
Step-by-step explanation:
Step 1:
Let us assume that Joshua's Car consumes 10.3 gallons of fuel to drive 418.1 miles( 672.86 km).
Now we have to find how much fuel will Joshua's car consume to drive 100 km.
It is in direct proportion.
Step 2:
For 672.86 km it consumes 10.3 gallons.
For 100 km it will consume X gallons.
(672.86 / 100) = (10.3 / X)
X = ( 10.3 × 100) / (672.86)
= 1.53 gallons
