Qualcomm Embedded Software Engineer Interview Question

I interviewed in Boulder, CO and was asked:
"A brain teaser question where we have to find out 45 minutes with the help of two ropes. Given that one rope burns completely in 1 Hr and the rate or burning is not consistent."

I assume that both ropes have the same non consistency.
If you burn from one end it takes 1H.
If you burn it from both ends it takes 1/2 H.
To get 1/4 H, burn it from both ends and the point that in the first rope the fires got together.

Immediately after the first rope burnt, burn the second rope from one end and the middle point that fires reached each other in the first rope.
To get 1/4 H, burn it from both ends and the point that in the first rope the fires got together.
