To solve this, simply cross set up a proportion.
1 : 20
x : 1200
when you cross multiply, you will be left with
20x = 1200
x = 60
Therefore, 60 gallons
Or
Speed = 20mi/gal
1200mi x 1gal/20mi = 60 gallons
1200 miles @ 20 miles per gallon means 1200/20 = 60 gallons. 60 gallons @ 2.99 per gallon = 179.40
If I can travel 450 miles in 2 hours, I can travel 450 ÷ 2 = 225 miles in 1 hour. As I can travel 225 miles in each hour, I can travel 1200 miles in: 1200 ÷ 225 = 51/3 hours = 5 hours 20 minutes.
Roughly 1200.
1 hour = 60 minutes 20 gallons / 1 minute = x gallons / 60 minutes Solve the equation for the amount of gallons per hour 60 min x 20 gallon / 1 = x x = 1200 gallons/minute
First, determine how many gallons it will take: 1200 mi ÷ 30 mi/gal = 40 gal. Then, figure out how much it'll cost: $4.20/gal × 40 gal = $168.00 A useful idea is to keep the units with the calculation, and verify that your method makes sense by checking that you get sensible units. You can tell something is wrong, if you end up with the price being miles/$ or something silly like that.
1200 miles @ 20 miles per gallon means 1200/20 = 60 gallons. 60 gallons @ 2.99 per gallon = 179.40
1200 miles @ 19 miles to the gallon = 1200/19 = 63.2 gallons. The price does not alter the amount of gas required.
Divide the number of miles by miles per gallon = 1200 / 32 = 37.5 gallons.
1200/25 = 48 gallons
1,200 miles at 12 miles per gallon = 100 gallons.100 gallons at $3.50 per gallon = $350 .
This one's easy ... 1200 miles, divided by 22 mpg = 54.5 gallons. 54.5 gallons times $1.95 per gallon = $106.28 for your gas money.
A simple division problem should yield our answer: 1200 miles ÷ 10 miles/gallon = 120 gallons. Therefore to drive 1200 miles in a vehicle that consumes a gallon of gasoline every 10 miles would require 120 gallons of gas. (Which at approximately $3.50, would be very costly).
Assuming a car that gets an average of 25 miles per gallon, it would take 48 gallons of gas to drive 1200 miles.
66 2/3 gallons
Around 54 gallons
Approx. 25 miles/gal (combination highway and around town)? 1200 miles/25 = 48 gallons required 48 gallons X $4.00/gal (approx. price/gallon) = $192.00
