A roundtrip from Fort Collins, CO to Lubbock, TX and back to Fort Collins is 1,200 miles.
It took Mr. P and his wife 20 hours for the roundtrip
but those 20 hours included their pit stops.
If they stopped for a total of 1 hour 50 minutes,
how fast did they average (in mph to the nearest tenth) over the whole trip?
Solution to the Problem:
Mr. P and his wife averaged 66.1 mph.
Subtract 1 hour 50 minutes from 20 hours to get 18 hours 10 minutes.
Divide 1200 by 18 hours 10 minutes (or 18.1666... hours) to get 66.055 mph.
