The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by, an = a1 + (n - 1) x d Substituting, an = 40 + (15 - 1) x 20 = 320 Thus, the answer is letter B. 320 feet.
