1) She left Colorado at 1:45pm on Tuesday2) Time in Nebraska = 4:20pm CST3) Time of arrival in Alabama = 10:00pm CST (Friday)  Explanation:  1) Time of arrival in Illinois = 2:45pm CST (Wednesday)As Carrie total journey was of 24 hours.She left Colorado at +2:45 pm CST (Tuesday)As Colorado is under MST, and MST has difference of -1 (minus one) hour to CST.Time she left Colorado in MST =  2:45pm CST - 1 hour = 1:45pm MST (Tuesday)  2) Nebraska is under CST and New York is under EST.  Where CST has the time difference of -1 hour to ESTSo if Time in New York is = 5:20pm ESTTime in Nebraska is = 5:20pm EST - 1 hour = 4:20pm CST  3) Departure time = 5:00 am EST (Friday)Total journey = 18 hoursArrival time in Alabama = 5:00 am EST + 18 hours = 11:00pm EST (Friday)As Alabama is under CST , and CST has a time difference of -1 hour to EST, thenArrival time in Alabama = 11:00pm EST - 1 hour = 10:00pm CST

The answer is 3. -1/2 n + 1 1/2 n add the coefficients to get 1n or just n. then n-n is 0 what is left is 3.
