Question: In one cycle a heat engine absorbs 5 2 0 J from a high - temperature reservoir and expels 3 2 0 J to a

In one cycle a heat engine absorbs 520 J from a high-temperature reservoir and expels 320 J to a low-temperature reservoir. If the efficiency of this engine is 55% of the efficiency of a Carnot engine, what is the ratio of the low temperature to the high temperature in the Carnot engine?
