Given the ferris wheel's diameter is 44 ft, its radius is 22 ft. The wheel turns at 6 rpm, so in 30 seconds (half a minute), it completes 3 revolutions (6 rpm * 0.5 min = 3 revs). This means the passenger is back at the starting point, which is 4 ft off the ground, hence the correct answer is 4 ft.
