How far can helicopter fly on a one tank of gas
400
How far a bus can go on one tank of gas varies. It depends on the make and model of the bus, what fuel it uses, and how well it has been maintained.
Not enough info to answer that.
I just filled my Prius today (T-spirit, next Prius 09) and it says the full tank will do 453 miles. Just one data point.
Depends on the gas mileage of the vehicle. Huge difference between, say, a Prius and a Hummer.
It is a 15 gal. Gas tank on them cars I have one.
there isnt one
Depends on the size of the tank and the miles per gallon that vehicle gets. I have a truck that will travel 15 miles on one gallon, and a sedan that will travel 30 on the same gallon. I have one truck with a 10 gallon tank, another with a 20 gallon tank.
What backup gas tank , it doesn't have one
A Supermarine Spitfire can travel 423 miles on one tank of gas.
567 miles 27x21=567
