Question 640995
Hello, 
From the info given, it appears the traveler is 23 miles from Sac and 110 miles from Oakland going one way. If so, first subtract 23 from 110 to give us:
87 miles between Oak and Sac
Now divide this by 2:
43.5 miles is the distance midway between the two cities. 
Make sense?
