Write a rational function that models the problem's conditions.A plane flies a distance of 1790 miles in still air. The next day, the plane makes the return trip, however due to a tailwind, the average velocity on the return trip is 29 miles per hour faster than the average velocity on the outgoing trip. Express the total time required to complete the round trip, T, as a function of the average velocity on the outgoing trip, x.
A. T(x) = 
+ 
B. T(x) = 
+ 
C. T(x) = 
+ 
D. T(x) = 1790x + 1790(x + 29)
