John climbs up 3 flights of stairs.  Each flight is 10 feet.  He then climbs a rope that is half that height.  Finally, he climbs a ladder that is 10 feet longer than the rope.  How high up did he go?
How many feet did John climb? ** He climbed 3*10=<<3*10=30>>30 feet of stairs
How many feet did John climb on the rope? ** He then climbed 30/2=<<30/2=15>>15 feet of rope
How many feet did John climb on the ladder? ** Finally, he climbed a 15+10=<<15+10=25>>25 foot ladder
How many feet did John climb? ** So in total, he climbed 30+15+25=<<30+15+25=70>>70 feet
