Ben and jerry start with the same number of cards. after ben gives 12 cards to jerry, jerry has 2 times as many cards as ben. how many cards did ben have at the start?

12 i think i got confused

36 cards because 36 - 12 = 24 and 36 + 12 = 48

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.
