With each cycle a 2510-w engine extracts 2070 j from a

With each cycle, a 2510-W engine extracts 2070 J from a thermal reservoir at 90 °C and expels 1340 J into a thermal reservoir at 20 °C. What is the work done for each cycle? What is the engine's efficiency? (Be sure to enter your answer in decimal format and not as a percent.) How much time does each cycle take?
