Answer:
4.416 minutes
Explanation:
I assume the bottom of the Ferris wheel is at the height of the platform.
diameter = 68 m
radius = 34 m
platform height = 2 m
height of the center of the Ferris wheel = 36 m
36 m is 1 m above the center of the wheel
sin Θ = 1/34
Θ = 1.6854°
2Θ = 3.3708°
180° - 3.3708° = 176.6292°
176.6292/360 × 9 minutes = 4.416 minutes
