Naphthalene will sublime easily, Sodium Chloride will not.
Heat the mixture of Naphthalene and NaCl causing the Naphthalene to sublime into a gas. Place a cooled surface above the fumes (such as a flask filled with ice water). The cooled surface will cause the Naphthalene vapors to return to the solid phase. Meanwhile, the NaCl will remain in the original container since it will be unaffected by the heating process.
This is obviously the anwer your question is going for since it included the fact that Naphthalene sublimes easily and did not mention its solubility at all.

You already answered your own question.Since naphthalene sublimes easily with heat, just heat the mixture. The naphthalene will evaporate leaving the NaCl behind. If you need to save the naphthalene, use a distillation apparatus.

They probably want you to warm the mixture until the naphthalene sublimes off, and you catch it on a cooled surface.
But... why? Add distilled water to the mix, enough to dissolve all the NaCl. Naphthalene isn't particularly soluble in water. Run it through a millipore filter. Rinse with more distilled water. All your naphthalene will be caught by the filter, and all your NaCl will be dissolved in the water. You can vacuum-boil off the water from your NaCl.

last time i checked naphthalene was only slightly soluble with water. NaCl is soluble in water so you can dissolve the salt and the naphthalene will mostly stay out of solution.
next time look up the properties on chemfinder.com before you ask a question.

go on a website that will tell you how many calories you need to stay at the weight you are now, there's an option where it says phisical activity it would be in bed or hospital, then subtract 400 calories to lose weight. another thing is make a smoothie of juice from 4 oranges, juice from 1 grapefruit, a green apple sliced, 2 celery sticks, and a handful of cut nopales( a mexican item that is like cactus, make sure you take of the spines) you blend it together and you might need a glass of water added too, then you drink all of it, you could add a tablespoon of powdered flax seeds for more hunger control. if you get hungry later in the day take slim fast or a salad with light dressing. in five days i've lost a lot of inches and 10lbs. and I didn't even exercise just daily movements, and if anyone says it's unhealthy, it's not, people say that because when you lose weight fast and then you could easily go to your old habits, but its not unhealthy. don't throw up i know a girl that died because of it.

By heating we can get vapors of naphthalene and NaCl will be left as residue

Gee I remember this from Organic Chem too. When I got done, I had a perfect cube of the Naphtha moth ball.. I put it on the instructors desk to hand in. Somebody stole it and I got an "F" on the experiment. If you put the mixture in water,I believe the salt would be dissolved in the water and the remaining solid filtered out. After that I forget.

First, I'm really rusty on my chemistry, so consider that my answer might either be wrong or deadly.
That being said, in theory you could distill it by setting up a reflux-condensor like people use in sophomore organic chemistry.
