The distance between Atlanta, Georgia, and Albuquerque, New Mexico, is about 12 70 mi.
The groundspeed for jet traffic from Albuquerque to Atlanta can be about 18 % faster than the groundspeed from Atlanta to Albuquerque.
speed = 1.18r
Let r be the speed from Atlanta to Albuquerque in miles per hour.
T = 1270/r + 1270/1.18r
(1.18r*1270+1270r)/1.18r^2
(1270r(1.18+1))/1.18r^2
1076.27*2.18/r
2346.27/r
