To find Barry's altitude above sea level in inches when he is standing on the 55th step above the one-mile step, we first note that one mile equals 63,360 inches. Since he is on the 55th step above the one-mile step, we need to add the height of those steps to the one-mile measurement. If we assume each step is a standard height of 7 inches, then Barry's altitude would be 63,360 inches + (55 steps × 7 inches/step) = 63,360 inches + 385 inches = 63,745 inches.
