Part 1:
From a 220 feet high lighthouse in the Bahamas island of Nassau, a person sees a ship on the horizon. Due to the curvature of earth, how far is the ship from the lighthouse?

• Use the formula: d = sqrt[3h/2], where d is the distance in nautical miles and h is the height in feet.

Provide a similar example of when you were close to the beach, or elsewhere. Estimate how high above sea level you are and find how far the ship is from you.

Part 2:
An application of a rational function is T = (AB)/(A+B), which gives the time, T, it takes for two workers to complete a particular task where A & B represent the time it would take for each individual worker to complete the identical task working alone. It takes William 3 hours longer than Timothy to paint a 4x 5 feet bedroom. Respond to the following:

1. Working together, both can complete the job in 2 hours. How long does it take each one to complete the painting job working alone?


2. Provide a similar example, set up the equation and solve the problem.


3. Show you work step by step and explain your work step by step.


4. You should discuss the problem as if you tutor your classmates.
   
   
   
   • Compare your problem with that of two of your classmates.
   
   
   • Explain the differences on the set up of the equation.
   
   
   • Find possible errors and provide a better explanation or possibly clarifications.
   
   
   • Ask questions and engage into a discussion with your classmates.
