As the flight crew of a super MD80 increased their airspeed in compliance with the latest clearance instructions, ATC asked what speed they showed and advised to hold that speed now. Flight crew wondered if they should have stated that they were passing through the stated airspeed for the newly assigned airspeed.

Narrative:
On the civet profile, ATC advised us to maintain 330 KTS or greater. We started to increase from 280 KTS and as we were passing through 310 KTS ATC asked us what our airspeed was, and I replied 310 KTS. Perhaps a better response would have been 310 KTS increasing to 330 KTS. ATC's response was to maintain 310 KTS now.
