Just divide the distance by the time. If you want to have the answer in miles/hour, convert the time to hours first, and then do the division.

What is the speed of an automobile in kilometers per hour if it is traveling 45 miles per hour?

If the average velocity o nonzero for some time interval does this mean that the instantaneous velocity is never zero during this interval?
Not at all. Consider this example: -- I start out at 8:00 in the morning. -- I head east, drive 5 miles in 15 minutes, and park my car at 8:15. -- I go into my office, close the door, and spend the next 9-1/2 hours on Wiki.Answers. -- I leave the office exhausted at 5:45 in the evening. -- I head east again, drive another 5 miles in the next 15 minutes, and stop at a bar at 6:00. ==================================================== I left home 10 hours ago, and I am now 10 miles east of my home, enjoying a tall cold one. My average velocity for the 10 hours is 1 mile per hour east. The average is non-zero, even though I was at my desk playing computer games from 8:15 until 5:45. At any instant during 95% of the day, my instantaneous velocity was zero.
