ascending grade of 4.42% meets a descending grade of -5.45% which serves as tangents for a parabolic curve. What is the resulting length of this curve (in meters) if the sight distance is 111 m., height of driver's eye level from the road is 1.14 m. and height of the object from the road is 0.40 m.? Round off to two decimal places.

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.
