Maybe 2 minutes, maybe 4, maybe a bit less than 4 (-- maybe even a bit more). 
It depends on how the problem is truly defined.

If each man runs a half mile concurrently, then 2 minutes.
ANS - Neither man has completed the full one mile course, therefore the 
business world will NOT accept this

If they each run the full mile (and the slowest runs a mile in four minutes and 
we're timing to the point the last man crosses the finish line), then 4 minutes.
ANS - If the reliance is the slowest man, then why use 2 men. The business 
world will say, its costing twice the amount, to obtain the 4 minute result.

If it's a half-mile relay, then maybe a bit less than 4 minutes.
ANS - again why use 2 men when the second man does NOT see the path of the 
first man, what results would be obtained?

In short, if management judged this technique to be the same as something like 
running a mile, the results are "unpredictable".

Now, if the run included such elements as "you must step on every 'X' you find 
on the pavement along the way, and if you reach the finish line and find you 
missed one, you must go back to the 'X' previous to the one you missed and 
begin again from there; further, the designated letter may change at any point 
along the way to a 'Y' or 'Z' or any other letter -- there might be clues that 
tell you when a change is in effect", then it might easily be worthwhile to 
have a second set of eyes during the run.
ANS - Don't get me wrong, I'm all for obtaining the correct result, but at what 
cost? What cost-analysis studies have been performed  for either or both the 
single pair of eyes against the 2 pair of eyes. If it can be proven that 2 pair 
of eyes will result in a better/cheaper or safer product, then by all means go 
for it.

Otherwise 1 pair of eyes will do.
