Arailroad tunnel is shaped like a semi ellipse, as shown below. the height of the tunnel at the center is 27 ft, and the vertical clearance must be 9 ft at a point 24 ft from the center. find an equation for the ellipse.

Do standard algorithm 4 27 + 24 then add the 9 and then you got your answer and sending out gorillavids multiplication if you know what that means but that's all I can give you and I in 5th grade so I don't really know what you're doing so that's my best

The answer would be 13.5 minutes.
