Good news: The solution time has been extended till Friday as by technical reasons the newsletter didn't go on time.
You and your grandma live on the same side of the river. You need to find the shortest way to walk from your house to the river (with an empty bucket), fill the bucket with water and bring the water to your grandma. The river is fierce and you cannot swim in it. Disregard the fact that it is much harder to walk with a full bucket than with an empty one. Just look for the shortest path.
Note: the solution does not involve any equations, just one-two simple lines.... Feel free to print the image or redraw it. Submit your answers as images via email to me or in the comments on this blog post. Please explain your answer. The answers are accepted any time until midnight Eastern Time on Friday, on our Family Puzzle Marathon.
Friday is here and below is the answer drawing:
The shortest way is marked with a red line.
To find it draw a reflection of the grandma's house across the river and connect with a straight line Your house and the Reflection of Grandma's house. It surely is the shortest distance between these two points.
But Grandma lives on this side of the river! OK, just reflect the interval of the line from the river to Grandma's house.
