What is each number written in scientific notation? 1,220,000,000 1.22 x 10 0.122 x 10^10 12.2 x 100^8 1.22 x 10^9

The answer for you question is b

The first one is 2/3the second is 1/160the third is 4/125

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.
