20 miles per hour

1) Gathering the data from the question:

S=140 miles

Time spent =7 hours

Average speed=?

2) The average speed is calculated using a ratio:

$A\text{ =}(140)/(7)=\text{ 20}$

Since the units are in a standard usual way, we don't need to do any conversion so, the answer is

20 miles per hour
