A car could go 30 miles on 1 gallon of gas. How far could the car go on 8 gallons of gas?

8 * 30 = ?

240 miles.

To find out how far the car could go on 8 gallons of gas, you can use proportion. The proportion can be set up as follows:

miles/gallon = total miles/total gallons

Given that the car can go 30 miles on 1 gallon of gas, we can substitute these values into the proportion:

30 miles/1 gallon = total miles/8 gallons

To solve for the total miles, we cross-multiply and then divide:

30 miles * 8 gallons = 1 gallon * total miles

240 miles = total miles

Therefore, the car could go 240 miles on 8 gallons of gas.
