Her total time for 6 races must be under
6 x (5 5/6 min) = 35 min

Total time for the first five races is already ---. (Add them up). You seem to have made a mistake and listed six times, with 5 min 53 s appearing twice. Subtract the sum of her FIVE times from 35 minutes to find out how fast she must run the sizth race.

If the 5min 53 s time as supposed to appear only once, her total times so far add up to 27 min 134 s = 29 min 14 s. The last race must be run in under 5 min 46 s. That should be possible, since she has run that fast before.
