A person was going to go on a walk.  Before he started it, he was 0m away from his house(he was in it).  He walked at a fast, steady pace for the first 2 minutes.  He has walked 4m during the third minute.  However, at the fourth minute, he gets tired so he sits on a bench next to him to take a break for 3 minutes.  At the seventh minute, he gets up and starts to walk home.  During the tenth minute, he is back at his house and this concludes his walk for the day.
