Distance = Speed x Time
Time = Distance / Speed = 1200 miles / 65 Miles per Hour
18.4615385 Hours
To drive 80 miles at 80mph takes 1 hour. To drive 1200 at 80mph takes 1200/80 = 15 hours.

65 miles per hour .. In math, per is a key word that lets you know there is division. 65 miles / 1 hour = Speed 1200 miles / ? hour = 65/1 which is the same as ? hour/1200 miles = 1/65 ? hour = 1200/65 18.46 = how long it takes to drive 1200 miles at 65 mph.
1200/25 = 48 gallons
Assuming a car that gets an average of 25 miles per gallon, it would take 48 gallons of gas to drive 1200 miles.
1200 miles/(23m/g) = 52.17gallons
Divide the number of miles by miles per gallon = 1200 / 32 = 37.5 gallons.
