I live on the ground floor of a ten-story building. Each friend of mine lives on a different floor. One day, I put the numbers $1, 2, \ldots, 9$ into a hat and drew them randomly, one by one. I visited my friends in the order in which I drew their floor numbers. On average, how many meters did I travel by elevator, if the distance between each floor is 4 meters, and I took the elevator from each floor to the next one drawn?
