Answer:
2,452.12 L of fuel the jet consumes on a 1150 km mission.
Explanation:
Speed of the jet = 1300 km/h
1 hour = 60 minutes

Rate at which jet consumes fuel = 46.2 L/min
Distance covered by jet by consuming 1 liter fuel or mileage = R
R = 
The amount of fuel the jet consumes on a 1150 km mission will = V
Amount of fuel = 

2,452.12 L of fuel the jet consumes on a 1150 km mission.
