Answer 1

A plane has 270 gallons of fuel. The plane's average fuel consumption  is 1 7/9 miles per gallon. How far can the plane go ?  Assuming that the conditions over which the 16/9 m.p.g. rating is obtained are the same, this flight will go

 

Dist (miles) = (270 gallons)(16/9 miles/gallon) = 480.

 

In practice, that's not how to plan a trip--you have to plan to land within that distance, safely, refuel, and continue on living.
