From the information given, there is no way to tell.
But if we assume David traveled 65 mph for 2 hours,
and his friend travels 40 mph for 0.25 hr, we get:
(40mph)(0.25hr)+(65mph)(2hr)=10mi+130mi)=140 miles
However, given the question, how far did his friend drive
before he slowed down to enter the village?
No way to answer this question precisely given the
insufficient information.
