try to figure this out ;)
A hard working man usually arrives to the train station of his home town each day at 5 AM
His wife picks him up, and drives him the rest of the way home. (He is a hard worker, so when he comes home, she takes care of him)
One day the man gets of from work a little earlier, and arrives at the train station at 4 AM.
But instead of calling the wife, and have her pick him up sooner, he decides to walk till they meat somewhere on the road.
After he has walked for some time, he meats the wife, and she picks him up and takes him home.
They arrive at home 10 min sooner than they do when he arrives at the train station at 5 AM.
If she left the house same time as she always do.
And drove with the same speed as she always do.
For how long a time did the man walk, before he meat his wife ??
