Can you work this one out?

Question

Four men have to cross a bridge.
It takes one man 1 minute to cross, one man 2 minutes, another 5 minutes, and the last 10 minutes. Two have to cross at the same time. But if 1 minute goes with 5 minutes it will take 5 mintues to cross. When two have crossed one has to come back., untill all have crossed. (You must add that time too) Get all four men across in 17 minutes.

Answer 1

I liked this one it took some thought...

Well:

Man 1 + 2 cross the bridge = 2 mins
Man 1 returns = 1 min
Man 3 + 4 cross the bridge = 10 mins
Man 2 returns = 2 mins
Man 1 + 2 cross = 2

Total is 17 minutes.


Thanks for killing some time.

Answer 2

First man 1 and man 2 walk across the bridge. This takes 2 minutes.
After this, man 1 walks back. This takes 1 minute.
Then man 3 and man 4 walk across the bridge. This takes 10 minutes.
After this, man 2 walks back. This takes 2 minutes.
Then man 1 and man 2 walk across the bridge. This takes 2 minutes as before.
In total: 2+1+10+2+2=17 minutes.

Answer 3

1 minute man and 10 minute man cross = 10 minutes
1 minute man comes back = 11 minutes
5 minute man and 2 minute man cross = 16 minutes
then 1 minute man crosses = 17 minutes

Answer 4

ok i cant work that out, got lost at "But if 1 minute goes with 5 minutes..."

however, is there no water underneath the bridge in which they cud swim? that would take less than 17 mins....

or perhaps a round route, or an alternative path they could take?

Answer 5

1min + 2min cross = 2
1min back = 3
5min + 10min cross = 13
2min back = 15
1min + 2min cross = 17


Or something like that.....

Answer 6

can't they swim the at same time?
if the bridge is too hard to pass

Answer 7

Put them all in a giant catapult.
