Question 986394
"it consumes fuel at a rate of 38 l/min. if the jet's fuel tanks contain 6840 l when full"
Assume the tank is completely full. This means the plane can fly for ( 6840 L )*(1 min/38 L) = 6840/38 = 180 minutes


180 minutes = (180 minutes)*(1 hour/60 minutes)
180 minutes = 3 hours


It can fly for 3 hours on a full tank with light winds. 


D = r*t
D = 700*3
D = 2,100


The jet's maximum range is <font color="red">2,100 km</font> with a full tank and light winds.
