Zynga interview questions

What would you do if you had enough budget and wanted to take the team out ?

You have two variable lengths of rope with different widths at different sections of the rope and both of them burn at different rates and speeds, they only thing you know about them is that they both burn in exactly 30 minutes. You also have two matches. Just using these two things, how would you measure 45 minutes of time? (Also, you have no way to measure time, i.e. - no wrist watch, etc.)
