With all of the talk about high gasoline prices, I thought that it might be interesting to track how much gasoline we will use while on vacation.
To The Condo Estimates: Distance And Speeds
Distance between our house and the condo (one way) = 287 miles
Travel speeds between our house and the condo (average) = 60-80 mph
Most of the trip (276 miles of it) will be spent driving on the interstate. 11 miles of the trip will be on standard highways and roads. For calculations sake, I’ll assume an average speed of 70 mph.
To The Condo Estimates: Travel Time
Time between our house and the condo (one way) = 287 miles / 70 mph = 4 hours and 6 minutes
Time spent stopping to eat lunch and take breaks for the kids = 1 hour
Total estimated travel time = 5 hours and 6 minutes
To The Estimates Estimates: Gasoline Usage
Average miles per gallon of gasoline = 21 mpg
Our van has a digital gauge which measures, among other things, miles per gallon and miles left until tank is empty. Tomorrow, I’ll fill up and make a note of how much I put into the 20 gallon tank. Over the past two weeks, the van has averaged 21.4 mpg. During the trip, our family of five, plus all of our luggage and stuff for the new baby will be packed into the van, so I’m assuming that the average miles per gallon will decrease, at least a little.
Gallons of gas used = 287 miles / 21 mpg = 13.66 gallons of gasoline
Cost of a gallon of gasoline = $3.80
Estimated gasoline cost to go to the condominiums = 13.66 gallons = $51.91
I’m a pretty average driver. I like to hit the interstate, set my cruise control on about 75 and just ride. Today, I changed the oil in the van, checked the tires, and changed the air filter. The back of the van will be loaded down with our suit cases and a small cargo bag will ride on top of the van. Once we arrive and get settled, I’ll let you know if I did a good job of estimating our travel time, the amount of gasoline we used, and the cost of gas.
