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.
