WILL GIVE BRAINLIEST URGENT
The total time T (in hours) needed to fly from New York to Los Angeles and back can be modeled by the equation below, where d is the distance (in miles) each way, a, is the average airplane speed (in miles per hour), and j is the average speed (in miles per hour) of the jet stream. Simplify the equation. Then find the total time it takes to fly 2468 miles when a = 510 miles per hour and j = 115 miles per hour.

T = d/ a − j + d / a + j
