if we have two sticks with the same dimentions

each one of them take one hour to be full burned

the burning operation is with constant rate

regardless the direction of burning

so , with the burning operation and only the burning operaiton

how can we calculate fourty five (45) minutes .

note :

for those who know the answer honorly let others try ,and do not burn :D the conundrum .


peace be upon you

what about this one, if you have two sections of a forum, one called Linux-Support/General and the other called Community-Center/General-Chat and you have an extremly off topic question in mind and the rate of posting is constant how to determine which forum to post to??

note:
for those who know and respect guidlines honorly let others try, and do not burn them.

well, may be # uptime will do ?

u didnt specify whether after these 45 mins u want them fully burned or not so I guessed not.

So I could place one of the sticks at a right angle to the other stick and apart one-quarter from one of its sides and then then start firing from the other side.

When fire reaches the angled stick then 45 mins passed or calculated.

nice try , but i am sorry it is not the right answer

we do not know the quarter from the half and we do not have

the tools to do so .

i must be having a big leak of memory , ok the two sticks will

be full burned , any way akh sattia by this nice try to answer

you have the right to ask for the answer , if so i will post to

you pm with the answer to let others try

or you can take another chance ;)

peace be upon you

^ after 30 mins start firing here

well
what if we burn one of the sticks from both sides; this way it would burn with double the rate; or it would take only 30 mins and at the same time burn the other from one side only
After 30 mins we have the following:
one of the sticks is fully burned
the other is half-burned and it still needs another 30 mins to burn; so we can burn the other side to again double the rate of burning and hence half the time required to 15 mins.
now we have 30 + 15 = 45 mins
