Answer:
2 hour 50 minutes
Step-by-step explanation:
Given data: Departure = 5:30 pm MST, Arrive = 9:20 pm CST
Note that MST is the time zone 1 hour before CST.
Let us convert MST into CST.
Departure = 5:30 pm MST = 6:30 pm CST
Total time travel = Departure – Arrival
= 9.20 pm MST – 6.30 pm MST
= 2 hour 50 minutes
Hence, total time travel is 2 hour 50 minutes.
