A clock takes 7 seconds to ring bell at 7 o'clock. How long will it take for the same clock to ring bell at 10 o'clock?

• 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.

• in between ringing 7 times gap are 6
  so in 10 times are 9
  6 gaps .....7 sec
  9 gaps...... (7/6)*9 =10.5 sec

• bong--bong--bong--bong--bong--bong--bong in this -- represent time -- are 6 so 7/6= for one gap 1.16
  hence for 10 time it gives nine gap 1.16*9= 10.5
  
  10.5 write time
