Answer:
1cm: 1 km
Step-by-step explanation:
The scale of the map is simply 1:1
Gas mileage = 30.5 mi/gal
Volume of gas = 1.5 l
Note that 1 liter = 0.264172 gallons
Therefore
1.5 l = (1.5 l)*(0.264172 gal/l) = 0.3963 gal
Distance traveled is (Gas mileage, mi/gal)*(Gal of gas)
= (30.5)(0.3963) = 12.087 mi
Answer: 12 mi (nearest integer)
Just divide both sides of the equation by -12 and you get your answer. Hope that helped!
