Right, I'm the Dad. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> Firstly I take Mum across. Then I come back and get Grandma and take her across and come back. Totally time 5+1+2+1=9 minutes.
I've got 8 minutes left to get myself and old Grandpa across. But it's a flaming torch, right? So I apply it to the old boy's backside. With fire streaming from the back of his trousers he makes it across in 1 minute flat with me in hot pursuit.... <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" /> No? You still won't accept it? <img src="/ubbthreads/images/graemlins/eek.gif" alt="" />
Right, I'm "fit and healthy", so with the incentive of the Secret Police looming, I give Grandpa the torch to hold, pick him up and CARRY him across on my back. Giving another human a piggy-back is EASY, particularly a shrivelled old goat like him! We're home with time to spare. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
OK, I've been kidding around here (even though I like ALL my solutions). Here's my final answer:
<span class='standouttext'>Spoiler : </span><span class='spoiler'> I'd take Grandma across first and go back (3 minutes used)
I'd give the torch to Mum and Grandpa. They'd cross together (13minutes gone now)
Then Grandma brings the torch back to me (15 minutes gone)
The two of us cross to safety (in exactly 17 minutes)
And THEN Grandpa opens up with his Uzi <img src="/ubbthreads/images/graemlins/stupid.gif" alt="" />
</span>
Unfortunately, I'm to exhausted from all this exercise to even try crossing the second bridge today... <img src="/ubbthreads/images/graemlins/sleepey.gif" alt="" />
