On Friday, Jan hiked in the woods. If she hiked a vertical distance of 60 meters relative to sea level and then down 86 meters, where would she be relative to sea level if she started at 0?

Answer 1

If "down" is also the vertical distance, then she'd be 26m below the sea level. I hope there's a dike.
