Final answer:
A car can drive 112 miles on 8 gallons of gas.
Step-by-step explanation:
To find out how far the car can drive on 8 gallons of gas, we can set up a proportion using the given information. Since the car drives 840 miles on 60 gallons of gas, we can say that 1 gallon of gas can make the car drive 840/60 = 14 miles. Therefore, 8 gallons of gas can make the car drive 14 x 8 = 112 miles.
