Plz now! i might fail and idk im dum! manoj rappelled 30 ft down from the top of a canyon. he then rappelled an additional 10 ft down the canyon. what must he do to return to the top of the canyon? select from the drop-down menus to correctly complete the statement.

If rappelled means he fall down, I'd say he's need to climb 40 feet up. Because he rappelled 30 feet down, -30 feet from where he used to be, and then he fell an additional 10 feet down, so -10 from the -30, which is -40. He needs +40 feet to get back up. I'd say the answer's 40 feet climb.
