I need to know times to different places in paris.?

Okay so can someone tell me the walking times from these places and how much time I should probably spend in each? I was thinking about starting in the place de la concorde then going to the louvre then to le madeleine and then to the opera to finish off the night. Can someone tell me the walking distance and how long it'd take to get to each place and maybe how much time I should spend in each? This is for a project so and these have to be seen in one day. Thanks for your help! Best answer gets 10 points!!!
