Boat Landing Problem - Classroom/Home Simulator and Build your own Simulator by LFS  
 

Problem setting: A man with a boat at point S at sea wants to get to point Q inland. Point S is distance d1 from the closest point P on the shore, point Q is distance d2 from the closest point T on the shore. The points P and T are at a distance of d from each other.
 

Question: If the man rows with a speed of vr and walks with a speed of vw at what point R should he beach the boat in order to get from point S to point Q in the least possible time?

 

An interesting problem made accessible for 8th-10th graders using GeoGebra. Try the simulator below or view animated demo.

 
GeoGebra InterActivity Directions for InterActivity READ ME FIRST!

1. To use: Click and drag input parameters to desired values.

2. Then click the slider point red for R (don't drag; you need to see the point glow red_glow). Then you can use arrow keys to find minimum Time.

 
Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Comments This is an interesting problem - it requires only Pythagoras' theorem and distance-rate-time formula to set up and run a simulation. It is easy to understand different aspects of it and to have many discussions. Good for 8th-10th grade. Then later in AP Calculus, one can move to the actual "mathematical solution", which is an extreme value problem also with wide ranging discussions!
