You have discovered that you have two Twizzlers have some really interesting properties.

When lit on fire, each Twizzler will burn for exactly 1 hour.
The rate of burning is NOT constant – different parts of each Twizzler burn at different rates,
AND each Twizzler burns at a rate different from the other.
You need to use these two Twizzlers to measure EXACTLY 45 minutes. How do you do it?

Interesting question but CHALLENGE ACCEPTED

Since we know that with one flame the Twizzler will burn for 1 hour, with two Twizzler should burn for 30 minutes

So to start off, you light one Twizzler at both ends and the other twizzler only at one end simultaneously and

Once the Twizzler with both flames has burned out we know 30 minutes have elapsed and we only have 30 more minutes left on the other Twizzler

At this exact moment, we light the unlit end of the remaing Twizzler to half its remaing 30 minutes to exactly 15 minutes.

This means when this Twizzler burns out in exactly 45 minutes

*LAUGHS IN GENIUS*
