Shortly after her run, officials realized that the timing mechanism malfunctioned. The stopwatch did not begin timing her until 11/25 of a minute after she began to run. If the time was otherwise correct, how long did it actually take Nuria to run the mile?

Solution:

11/25 minutes is 11/25 x 60 = 11/5 x 12 = 26.4 seconds

Thus, her actual time was 5 minutes 44 seconds + 26.4 seconds = 5 minutes 70.4 seconds = 6 minutes 10.4 seconds

44 seconds is about 3/4 of a minute.
11/25 is almost another half minute.

Adding these two clearly exceeds a minute. The only answer in the 6 minute range is E.
