Can someone explain what this means?

T=d/r 6/r - 6/(r+1) = 18/60 in hours 1/r - 1/(r+1) = 1/20 (r+1-r)/r(r+1)=1/20 r(r+1)=20 4(5)=20 r=4 mph r^2+r-20=0 (r+5)(r-4)=0 r=4 or -5 (reject).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
