Alvine just got a popsicle from an ice cream truck while she sits on a bench waiting for her friend to meet her. She keeps the popsicle in its wrapper until her friend joins her in case her friend wants to buy a popsicle too and enjoy it with her. The problem is that while she's waiting, she puts it next to her on a bench in direct sunlight, and the popsicle is absorbing energy from the sun and the bench at a total rate of 2$\mathrm{}0$W.$.$  

 

 

 The popsicle has a mass of about $100$g is made almost entirely of water, and it was sitting in a freezer with temp equal to roughly −$17$ degree Celcius for a long time before she bought it.$.$  Alvine's friend finally shows up,$,$ and when she opens the popsicle wrapper, the popsicle has melted completely, but the resulting popsicle liquid is still 0$0$ segree Celcius. How long did it take ($($in minutes)$)$ for her friend to arrive? 

 

 

 Note that the specific heat of ice is 2090$\mathrm{}$ J/($/($kgK)$)$ and the latent heat of fusion of water is 334,000$\mathrm{}\mathrm{}\mathrm{}\mathrm{}\mathrm{}\mathrm{}$ J/$/$kg
