Hard math question

Distance is  6km  

  I had all of the calcs entered and tried to post it but the server crashed and it all went away.  I do not like the new overhaul of the website...this has happened several times.....site used to auto save input, but it does not anymore.

Let T be the time, in hours, that it takes Linus to travel down the mountain.....so......the time to travel up is T + 1  hours.......so

R * T   = D

3 (T + 1) = 6 * T     simplify

3T + 3   = 6T        subtract 3T from both sides

3 = 3T            divide both sides by 3

1 hour  =  T

So.....the distance  =  6 * 1 hr  =   6 km

I agree with EP on some points.....the site has a "leaner" look and you can award yourself - 1 point - for a good answer.....however.....it has crashed on me, too.....I also like the "AutoSave" feature...."crashing" while entering a long answer won't be cool....!!!!!
