30 gallons. Simple really.
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.
20mi = 1gal 555mi x (1gal/20mi) = 27.27gal
480 miles @ 20 miles per gallon = 24 gallons needed 24 gallons @ $3.75 per gallon = $90
This is a two part problem. First, you must determine the number of miles you can travel on one gallon of gas if it takes two gallons to travel 44 miles. This can be solved by dividing the miles driven by the gallons used. In this problem that would be 44/2 or 22 miles per gallon.Next, if you can travel 22 miles on one gallon, you want to determine how many gallons would be required to travel 528 miles. This can be solved by dividing 528 by 22 or 528/22 which equals 24 gallons.
Total trip mileage = 758. MPG 14 miles per gallon. 758 miles * 1 gallon/14 miles = 54.14 gallons $3.20 per gallon * 54.14 gallons = $173.25
247.5 miles
It will depend solely on the car that one drives. For instance: If I drive a Toyota Prius which gets 54 miles to the gallon- 460/54= x 8.51 gallons of gas should suffice (depending of traffic and road conditions) However if I drove a Hummer V1 (12 miles to the gallon) 460/12=x 38.3 gallons would be needed.
515 miles divided by 22mpg is 23.4 gallons used. 23.4 gallons times 2.50 a gallon is 58.50.
400 miles at 25 miles per gallon = 400/25 gallons = 16 gallons. 16 gallons at 4 per gallon = 16*4 = 64 units of currency.
1800 miles @ 40 miles per gallon = 1800/40 = 45 gallons 45 gallons @ 4.00 a gallon = 45*4.00 = 180.00
1200 miles @ 20 miles per gallon means 1200/20 = 60 gallons. 60 gallons @ 2.99 per gallon = 179.40
at 20miles per gallon it would take 7.25 gallons at 25miles per gallon it would take 5.80 gallons at 30miles per gallon it would take 4.83 gallons it depends on the efficiency of your car
