Question

the distance between Atlanta, Georgia, and Albuquerque, New Mexico, is about 1270 mi. The groundspeed for jet traffic from Albuquerque to Atlanta can be about 18% faster than the groundspeed from Atlanta to Albuquerque. Let R be the speed from Atlanta to Albuquerque in miles per hour. What is a simplified expression for the round-trip flying time?

Answer 1

ATL to AL is 1270mi

Speed = dist/time
ALB to ATL is 18% faster.

Means ATL to ALB will be: R
And ALB to ATL: R + 18%of R.

Answer 2

Total time = ALB to ATL + ATL to ALB

Time = dist/speed.
so,

\[\text{total time} = \frac{1270}{R+0.18R} + \frac{1270}{R}\]

Answer 3

Yes, i guess I'm right.

Answer 4

Umm, no.
