Does liquid water freeze at the same temperature at which ice melts?

I suppose the questioner is wondering whether a quantity of water in solid form (that is, ice) will take longer to turn back into liquid water (that is, to melt) than the liquid water took to freeze in the first place! That is a fascinating question, but it shows a bit of a misunderstanding regarding heat, energy, and heat transfer. Without more info, there's simply no way of answering the question, because there's a lot more involved than just time. An ice cube may take up to an hour to form in the freezer but may melt on the kitchen floor in a few minutes. That gives the impression that water melts faster than it freezes. On the other hand, frost may form on the windshield of your car almost instantly under the right conditions but may take a few minutes to melt after you turn the defroster on. That gives the impression that water freezes faster than it melts. Further, you may have noticed that an ice cube melts much more quickly when placed in a metal sauce pan than when placed in a wooden salad bowl. It all has to do with heat transfer. The faster heat can be drawn away from an object, the faster it will cool down -- and freeze eventually. The faster you can transfer heat to an object, the quicker it will heat up -- and melt eventually.
