Physics

A skier wears a jacket filled with goose down that is 15mm thick. Another skier wears a wool sweater that is 7.0mm thick. Both have the same surface area. Assuming the temperature difference between the inner and outer surfaces of each garment is the same, calculate the ratio(wool/goose down) of the heat lost due to conduction during the same time interval.

Isnt heat flow directly proportional to the distance?
