He is 77 ft above ground when he stops
Answer: I believe the answer is 77 feet
Step-by-step explanation: Once you finish the math(5+6-8+4=7), you end up with John 7 flights of stairs up. You then take 7 and then multiply it by 11 to get 77 feet above the ground when he stops. This is assuming that the flights of stairs are stories high.
