Answer:

B. 15 gallons

Step-by-step explanation:

We don't need an exact answer, so we estimate

To do this, we round

41 is a tens number, so I'm going to round to the nearest 10

40

612.9 is a hundreds number, so I'm rounding to the nearest hundred

600

for EACH gallon, the car drives(roughly) 40 miles. If I have driven(roughly) 600 miles, that means I have used 600/40=15 gallons
