56 + 32 as the product of the gcf and a sum.

Ok so we find the GCF of both numbers, we know that they are both multiples of 8, so 56/8=7 and 32/8=4. So with distributive property, we write 8(7+4). Although, already into the answer, i don't understand by "and a sum" so i'm stumped there

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.
