surely if it was 1.5 strikes per second then 7 strikes would take

7/1.5 seconds

=

4.67 seconds

and 3 strikes would take 2 seconds...

It would, which is why I typed 1.5 seconds per strike. I have no idea why it has shown up the other way round, but I suspect my computer hates me. It also keeps calling me Dave for some reason. :w00t:

But these answers all ignore the duration of the initial strike:

|Strike|Pause|Strike|Pause|Strike| = 3 seconds 3S+2P=3
|Strike|Pause|Strike|Pause|Strike|Pause|Strike|Pause|Strike|Pause|Strike|Pause|Strike = n seconds 7S+6P=n

You cannot solve this without knowing either the duration of the strike or the duration of the pause. All you can say is that n=9-(2*strike duration) and n=7+(4/3*pause duration)

Eg If the strike time is 1s and there is no pause it will take 7 seconds
If the strike time is 0.8s and the pause time is 0.3s it would take 7.4 seconds
If the strike time is 0.2s and the pause time is 1.2s it would take 8.6 seconds

Yeah , you see that's what I was just writing :whistling: :-D :oops: (not)

I guess the point is the strike cannot take zero time, so the answer is definately less than 9 seconds, and the pause cannot take zero time, so the answer is definately longer than 7 seconds...

(1.5 seconds per strike)

7/1.5 seconds

=

4.67 seconds

and 3 strikes would take 2 seconds...

3 seconds to strike 3

3/3 = 1 strike per second

7 strikes = 7 seconds..........

7/1.5 seconds

=

4.67 seconds

and 3 strikes would take 2 seconds...

(Thank you :oops:)

Correct. :thumbsup:

3 seconds, 3 strikes = 1.5 per interval

7 strikes = 6 intervals

So 6*1.5 = 9 seconds.

Those who said 10.5 seconds are doing a different version of the riddle (you googled maybe?) this is why I fiddled with the numbers! :roll:

(you googled maybe?)this is why I fiddled with the numbers! :roll:Hey, I resent that! :p

I knew that the first strike started at 0, so it's 2 strikes in 3 seconds, or 1 strike every 1.5 seconds.

7 Strikes x 1.5 seconds = 10.5 seconds.

In my answer though, I forgot to take into account that the first strike still doesn't count, so like you say, it should have been 6 x 1.5 = 9

3 seconds, 3 strikes = 1.5 per interval

7 strikes = 6 intervals

So 6*1.5 = 9 seconds.

assuming that the strike takes zero time?

3 seconds, 3 strikes = 1.5 per interval

7 strikes = 6 intervals

So 6*1.5 = 9 seconds.

Write that out in a time line, it doesn't appear to add up.

I think that this Dave thing has gone too far - TV channel, n-s;what's next?

Seconds - Strikes

0.0 - 1

1.5 - 2

3.0 - 3

4.5 - 4

6.0 - 5

7.5 - 6

9.0 - 7

Prime Minister? :w00t:

ohhhhh! I never thought of that. What have I said?:w00t:

Cuz Im Deaf

|Strike|Pause|Strike|Pause|Strike| = 3 seconds 3S+2P=3

|Strike|Pause|Strike|Pause|Strike|Pause|Strike|Pause|Strike|Pause|Strike|Pause|Strike = n seconds 7S+6P=n

You cannot solve this without knowing either the duration of the strike or the duration of the pause. All you can say is that n=9-(2*strike duration) and n=7+(4/3*pause duration)

Eg If the strike time is 1s and there is no pause it will take 7 seconds

If the strike time is 0.8s and the pause time is 0.3s it would take 7.4 seconds

If the strike time is 0.2s and the pause time is 1.2s it would take 8.6 seconds
