Respuesta :
After 18 hours of flight the plane will have used more fuel than it can carry, so it must stop at 16 hours to refuel.
Linear equations
Given that the Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel, to determine, using a linear, the amount of gasoline that is present on the Jet after it has been in flight for 18 hours without stopping to refuel, the following calculation must be made:
- 422000 - 369250 = X
- 52750 = X
- Every 2 hours, the plane uses 52,750 gallons of fuel.
- 18 / 2 = 9
- 52750 x 9 = 474750
- 422000 - 474750 = 52750
Therefore, after 18 hours of flight the plane will have used more fuel than it can carry, so it must stop at 16 hours to refuel.
