a rectangle with a length of 9 inches and a width of 8 inches is divided in to squares of with sides of length 1 inch. One third of these squares are painted red , 1/8 of the remaining squares are painted green, and the others are left unpainted. How many squares are left unpainted?

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.
