Well if this is a math problem or something, you’re missing information to solve this. But if this is just a normal question about range, then yes, a Cessna 182 Skylane would be able to fly from Phoenix to El Paso without refueling.
A Cessna 182 Skylane has a range of 1,053 miles, and the distance from Phoenix to El Paso is around 350 miles by air and 430 miles on land on I-10 W. So yes, even just half fueled, a Cessna 182 Skylane would make it.
