[Gizmokid2005]

Lying there in the yard so neat was something very good to eat. It had neither flesh not bone, but in 21 days it walked alone. What is it?

ANSWER (Congrats Mathster): An egg.

NEXT RIDDLE:

Four members of a band are walking to a night concert. They decide to take a shortcut, but must cross a bridge. Luckily they have one flashlight. Because of the varying size of their instruments, it takes each member a different amount of time to cross the bridge - it takes the first person one minute, the second person two minutes, the third person five minutes and the fourth person ten minutes. They must cross the bridge in pairs, travelling at the slower speed so if the one minute person went with the ten minute person, it would take a total of ten minutes. Since there is only one flashlight, one person must come back across the bridge, then another pair can cross. They only have 17 minutes to cross the bridge and still get to the concert on time. What order should they cross to get everyone across and get to the concert?

[cauzomb]

They should all cross as one group at the pace of the slowest person to get across in ten minutes.

[Mathster]

It cant be done as the bridge must be crossed in pairs and there is no way to get the flashlight across.

does crossing back count against time?

[Gizmokid2005]

Yes it can be done.

And yes, crossing back counts against time.

[Mathster]

well, the one minute guy walking each across would take 19 minutes.

if anyone besides the 1 minute guy walks across with the flashlight, then it just adds to the time. or they throw the flashlight back across.

[Gizmokid2005]

You are wrong Mathster...you can't just use the 1 minute person EVERY time

What order should they cross to get everyone across and get to the concert?

ANSWER:
First, the one minute person and the two minute person must cross the bridge, for a total of two minutes. Then the one minute person should come back with flashlight - total of three minutes. The five minute person and the ten minute person cross together next, making the total thirteen minutes. Now the two minute person goes back and (total now fifteen minutes) and gets the one minute person and they cross together bringing the total to seventeen minutes.

[/SIZE]The bells of the clock tower signal six o'clock with 6 lound rings, taking 5 seconds to do so. How long will it take for the bells to signal twelve o'clock?

5 hours 59 minutes 55 seconds
Then it'll take 11 seconds for the bells to ring twelve times.

[TurcoLoco]

5 hours 59 minutes 55 seconds
Then it'll take 11 seconds for the bells to ring twelve times.

up until the 11 seconds I was in agreement but how did you figure 6 ring takes 5 seconds yet 12 rings take 11 (5x2=11)? Shouldn't it be more like 10seconds?
