a basketball is dropped from a height of 20 feet . if it bounces back up to a height that is exactly half of its previous height , and it stops bouncing after hitting the ground for the fourth time , then how many total feet will the ball have traveled after 2 full bounces .
initial distance = 40 feet first bounce = 20 feet up + 20 feet down = 40 feet second bouche = 10 feet up + 10 feet down = 20 feet total distance covered = 40 + 40 + 20 = 100 answer is e
subtract(subtract(subtract(subtract(multiply(add(divide(divide(divide(divide(20, 2), 2), 2), 2), add(add(add(add(add(add(20, divide(20, 2)), divide(20, 2)), divide(divide(20, 2), 2)), divide(divide(20, 2), 2)), divide(divide(divide(20, 2), 2), 2)), divide(divide(divide(20, 2), 2), 2))), 2), divide(divide(divide(20, 2), 2), 2)), divide(divide(divide(20, 2), 2), 2)), divide(divide(divide(20, 2), 2), 2)), divide(divide(divide(20, 2), 2), 2))
