Ответ:
16 miles per gallon.
Step-by-step explanation:
On Monday Marci filled her car's tank and the odometer read 32,461.3 miles.
On Friday she filled the tank again and the odometer read 32,659.7 miles
It took 12.4 gallons to fill the tank
The distance covered by the car from Monday to Friday = 32,659.7 miles - 32,461.3 miles = 198.4 miles
The car depleted 12.4 gallons of fuel after travelling for the 198.4 miles
So one gallon would take Marci's car:
miles
= 16 miles.
