10.5 seconds; in sense that timer starts at first ring and the first ring is at time t=0 seconds and 7th ring is at time t=7 seconds. So, in 7 seconds, only 2nd, 3rd, 4th, 5th, 6th, and 7th are to be considered. So, 6 rings in 7 seconds means 3 rings in 3.5 seconds. so, at 10, only 9 rings add to the timer, each 3 of which takes 3.5 seconds. so total = 3*3.5 = 10.5 seconds. i think i have read it somewhere, uhh... in some puzzle book.
