100%, but I doubt that we are prepared to do it. If nobody drove a motor vehicle, there would not be any traffic accidents. We'd have to live very differently but it is possible.
Lydia's speed on Tuesday was 180 miles divided by 3 hours, or 60 mph. If she then drove 7 hours at 60 mph, she drove 420 miles. Altogether, she drove 420 + 180 or 600 miles.

Fill up the vehicle that you are going to test until the tank is full. Reset the odometer trip meter to zero. Drive the vehicle until you have one quarter tank of fuel left. Stop and fill the vehicle until the tank is full. Look at the trip meter and write down the reading you have. Now divide the miles you drove by the gallons of gas it took to fill up the vehicle. Example: You drove 365 miles and used 13 gallons of fuel. 365÷13 = 28.07 miles per gallon. Do this with three tanks of fuel and you will get an average miles per gallon for your vehicle.
So you need to divide. Miles per gallon means the miles is in the numerator and gallons is the denominator. You may benefit from this article, which I wrote.
15 mpg (miles per gallon). The key to this 'word problem' is understanding that "miles to the gallon" or more commonly, 'miles per gallon', means DIVISION. So, 300 miles per 20 gallons means: (300 miles) / (20 gallons) = 15 miles per gallon.
Divide the miles by the gallons used. 315.5/11.4 = 27.6754386
You can't calculate that, since you don't know how many miles she drove, and there is not information to figure it out.

The number of miles driven divided by the amount of gallons to drive that distance. If you drove 330 miles and it took 10 gallons to refill the tank, then you got 33 miles per gallon. You are only able to compute this if you start with a full tank and then refill the tank back to full after you drove a certain distance or start with a specific amount of gas and drive till you run out of gas.
