1/7(14r+28)=2(r+2)???

After distributing you get this equation. 2r+4 =2r+4 since it's the same expression on both sides the answer would be r=All real numbers because no matter whatever real number u put for r it will come out the same on both sides

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.

2/1 or just 2. sorry if i get this wrong
