240/20 = 12
12 x 2.50 = 6 x 5 = 30
(1,100 miles) x (1 gallon/28 miles) x ($4/gallon) = $157.143 (rounded)
$26.60
That depends on the gas mileage your car gets and the cost of gas. If you get 20 miles per gallon at $4 a gallon, then cost is 1600/20 times 4 = $320
Depends on the MPG the vehicle you are driving gets and the price you pay for the fuel per gallon.
400 miles at 25 miles per gallon = 400/25 gallons = 16 gallons. 16 gallons at 4 per gallon = 16*4 = 64 units of currency.
The answer will depend on the cost of a gallon.
$129.55
If gas costs $3.75 per gallon, your car gets 32 miles per gallon, and you drive 1500 miles, it will cost $175.78. However, your miles per gallon is likely based on highway miles at a specific speed, and it is likely you will not always be at this speed so it may cost more.
