This one is playin on ma mind? - mas aircraft for pet dogs
An airplane is flying at a point 1500 kilometers back from its base and then. Because of the prevailing winds, the return trip will have one third more fuel than the outward journey. If the fuel for the round trip takes 525 liters how many liters are needed for the journey alone? Assuming a linear relationship between fuel economy and speed of the aircraft.

Fuel used to be G =
ReplyDeleteR = return fuel
G + R = 525 (da)
R = (1 + 1 / 3) G (da)
G + 4 / 3 G = (1 +4 / 3) = G ((3 +4) / 3) G = 7G / 3 = 525
G = 1575 / 7 = 225
R = 525 to 225 = 300
Going 225 gallons used, returned with 300 gallons. (and what could be the relationship between speed and fuel consumption)
