Reasoning and answer: Since someone running twice as fast a mile as another person would mean they complete the mile in half as much time, this means Tony would run a mile in 6 / 2 = 3 minutes since Tina's time was 6 minutes. Since Tom is three times as fast as Tina, for the same reasons as above this means his time is 6 / 3 = 2 minutes. Altogether then, the total time for all three is then 6 + 3 + 2 = 11 minutes.
The answer: 11
