Minimum time to cross the river - a puzzle - K-12 Math Problems
http://math-problems.math4teaching.com/puzzle-minimum-time-cross-river
Solutions, explanations, common errors. Algebraic Expressions Divisible by 3. What is the point of tangency – no calculus, please. Minimum time to cross the river – a puzzle. Jose, Carlos, Linda, and Anna need to cross a bridge. It was dark and they only have one torch which they need to use to cross the bridge. Each of them have crossed the bridge before alone. Jose can run and cross it for one minute. Carlos can also do it in two minutes. Write your answer and solutions in the comment section. Enjoy.

Solutions, explanations, common errors. What is the point of tangency – no calculus, please. Squares, Triangles, and Van-Aubel’s Theorem. In the figure, H is the midpoint of side BC of ΔABC. The points I and J are the intersection of the diagonals of square ABDE and square ACGF respectively, that is they are the centers of the square. Prove that IH and HJ are congruent and that angle IHJ is a right angle. You supply the text :-). You will need the mid-segment theorem. Posted by Erlina Ronda. How to orche...

Solutions, explanations, common errors. Minimum time to cross the river – a puzzle. Squares, Triangles, and Van-Aubel’s Theorem. What is the point of tangency – no calculus, please. Two lines intersect the graph. The secant line intersects the graph at point A and B and the tangent line which is parallel to the secant, touches the graph at point E. You can read the coordinates of A and B from the graph but not E. What are the coordinates of E? What are the equations of the two lines? Top Posts and Pages.
