Point a is at (-2, 4) and point m is at (2.5, 3.5).
point m is the midpoint of point 4 and point b.
what are the coordinates of point b?

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.

45 is the only number in both sets
