question

is it 1 degree???

If you have only one match and you walked into a room where there
was an oil burner, a kerosene lamp, and a wood burning stove, which
one would you light first?

Match

Right both of u, gud, now try this one:-

There are two lengths of rope.
Each one can burn in exactly one hour.
They are not necessarily of the same length or width as each other.
They also are not of uniform width (may be wider in middle than on the end), thus burning half of the rope is not necessarily 1/2 hour.

By burning the ropes, how do you measure exactly 45 minutes worth of time?
