**A reversible heat engine has an efficiency of 34.2%, removing heat from a hot reservoir and rejecting heat to a cold reservoir at 0°C. If the engine now operates in reverse, how long would it take to freeze 1.10 kg of water at 0°C, if it operates on a power of 183 W?**

I am getting stuck on how I can incorporate the kg of water and the power.

I don't know which equation to use that will let me use those constants and allow me to find time.
