HELP! I AM LOST! 'You have decided to become 1 structural engineer who specializes in roller coaster design.
Your job is to design your own roller coaster ride. To complete this task, please follow these steps:

The amusement park you are designing for gave you the following coaster requirements:
- your coaster ride must have at least 3 relative maxima and/or minima
- the ride length must be at least 4 minutes
- the coaster ride starts at 250 feet
- the ride dives below the ground into a tunnel at least once'

All I need is an equation in standard form that meets all these requirements. I can do the rest on my own. (I think)
