Find the midpoint of the line segment between the points (7, 13) and (-14, 19). O(-7, 9.5). O(3.5,6.5) O(10.5, 16) O (-3.5, 16)

The variables should add up to equal 1

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
