Answer:
6 liters of gasoline
Step-by-step explanation:
Since, 1 km = 0.6214 miles
Therefore, 100 km = 0.6214 × 100 = 62.14 miles
∵ For 431.8 miles of driving Joshua required amount of gasoline = 10.4 gallons
∴ For 1 mile of driving gasoline required = [tex]\frac{10.4}{431.8}[/tex] gallons
∴ Gasoline required to drive 62.14 miles = [tex]\frac{10.4}{431.8}\times 62.14[/tex] gallons
= 1.4967
≈ 1.5 gallons
∵ 1 gallon of gasoline = 3.8 liters
∴ 1.5 gallons of gasoline = 3.8×1.5
= 5.7
≈ 6 liters
The number of liters of fuel should be 6 liters.
Since distance of 431.8 miles, and it required 10.4 gallons of gasoline (petrol).
So,
Since, 1 km = 0.6214 miles
Now
100 km = 0.6214 × 100 = 62.14 miles
The number of liters should be
[tex]= 10.4 \div 431.8 \times 62.14 \times 3.8[/tex]
= 6 liters
