(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The power output of a car engine running at 1900 is 600 kilowatts per hour.

How much work is done per cycle if the engine's thermal efficiency is 30.0 percent

2. Relevant equations

thermal efficiency=w(out)/Q(hot)

3. The attempt at a solution

It wants the answer in KJ/s so i converted the kilowatts to KJ/sec then divided by rev/s then multiplied by .3. What am i doing wrong? Any help would be appreciated.
