Question

What is the travel time: Depart 9:30 am MST Arrive 1:30 pm PST ?

Answer 1

I got this answer on k12

Answer 2

3 hours; how I solved it is by converting both time zones into Coordinated Universal Time (UTC). MST is 7 hours behind the UTC, and PST is 8 hours behind (you can find this on the internet).

To convert 9:30 to UTC, subtract 7 hours:

`9:30 -7:00=2:30`
So, in UTC, the departure time was 2:30 AM

To convert 1:30 to UTC, subtract 8 hours (note that the time is 1:30 PM and not AM; so the time should be 13:30-- going by the 24 hour system):

`13:30-8:00=5:30`
So, in UTC, the arrival time was 5:30 AM

To find the total time traveled, you must subtract the arrival time by the departure time:

`5:30-2:30=3`;;
so the travel time would be 3 hrs

Hope this helped :)
