First, we have to know how many miles will the plane fly on 6 trips, we already know that each trip is 768 miles.
[tex]6*768=4608[/tex]
Now that we have the amount of miles the plane will fly in 6 trips, now we have to divide.
[tex]4608/13=354.461538462[/tex]
The plane must fly very slow, since it would take around 354 miles for the plane to complete its trips.
Have a nice day! :)
