Rate Problem on Practice GMAT

[ellabaro]

If it took Carlos 1/2 hr to cycle from his house to the library yesterday was the distance that he cycled > 6 miles? (1 mile = 5280 feet)

(1) The average speed at which Carlos cycled from his house to the library yesterday was > 16 feet per second.
(2) The average speed at which Carlos cycles from his hosue to the library yesterday was < 18 feet per second.

The correct answer is E, but I chose C thinking that 17 feet per second would answer the question. Can the time be even more detailed? 17.5 feet per second? If so does that have an impact on the end result? Where was I wrong with my thinking?

ellabaro, is this question from a GMAT Prep test or ManhattanGMAT CAT test? Either way, we have specific forums for both of those tests, so please repost in the appropriate forum. This forum is for general math questions. Thanks!

I see a forum for the Manhattan CAT exam but not for the GMAT Prep test. Can you please provide me more direction or a link to that specific forum? Appreciate it.
