When you heat water, the system absorbs heat. In this case, as water gets from solid to liquid you need to let heat "flows" into system.

To check your answer (18600 J) it is necessary to know the Latent Heat of fusion of water and multiply it by the mass of water.

Well, I found the value of Latent heat of Fusion of water:

Hf = 334.5 J / g hence:

H = (334.5 J /g)(55.8 g) = 18665.1 J

So, your answer is correct.

Good luck!
