Answer:

808 minutes

Explanation:

Let the time taken by Trent be A and the time taken by Lois be B.

The total time (T) it will take both of them if they work together is given by the equation below;

Total time (T) =   (AB)/(A+ B)

                      = (4040 x 1010)/(4040 + 1010)

                      = 4,080,400/5050

Total time      = 808 minutes.
