Can you answer Problem 2: Did it Gust Get Colder?

Have you ever been walking down the street on a cold day when suddenly a gust of wind makes you feel even colder? The wind chill can make the coldest days of winter even colder with just the slightest wind speed. The National Weather Service uses the formula:

to estimate what temperature it feels like when the wind is blowing at V miles per hour, and the air temperature is T degrees Fahrenheit. The formula requires a wind speed of at least 3 miles per hour, and a temperature at or below 50 degrees Fahrenheit. The reason for these requirements is that the formula is an approximation which only holds in a certain range. To test its limitations, suppose that the wind speed is exactly 3 miles per hour. If this formula worked across all temperatures, at what actual temperature T would the wind chill temperature be equal to T? Round your answer to the nearest degree Fahrenheit.
