Fuse on fire

This is an old-timer:
You let one string ignite from both end.
By the time the string is done, 15 minutes will elapse.
At that point you iginte another string at one end.
Second one burn for 30 minutes.
15+30 = 45

Yeah, but wasn't the goal of the whole exercise to get a total of 45 seconds to get away / drop the bomb down the airshaft / say a last prayer / whatever?
If you just light one fuse (whether on one end or on both doesn't really matter), let it burn out and then, by hand, light the other one, you might as well just start with the second fuse in the first place. Either way, you have 30 secs to get away before the bomb goes off.

Now, if you were to come up with some way to patch these two fuses together so that you light the first fuse and the bomb goes off after 45 seconds, _that_ would be smart. I haven't found one yet.

That's easy.

1. Tie both fuses end to end
2. Light the fuse
3. count to fifteen
4. NOW run away :)

There is nothing to say how resistant the fuse is toward being stopped by any particular materials.

My solution would be to burn one fuse for 15 seconds, then stop the burning.  Snip off the frayed end, and set it up.

Then off you go.
