Given the sets: A = {1, 2, 3, 6, 7, 9} and B = {2, 4, 6, 7, 8}. Find (A*upside down U*B). O A. {1, 4, 8, 9}
OB. {1, 2, 2, 3, 4, 6, 6, 7, 7, 8, 9}
O C. {1, 2, 3, 4, 6, 7, 8, 9}
OD. {2, 6, 7}

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.
