Digital Agent engineers solve complex puzzles for our customers every day. Can you solve the Puzzle we created for you?

You live in a cabin in the woods 2 miles due North of a stream that runs East-West. You are going to- your Grandma’s house for Thanksgiving, which is 1 mile North and 12 miles West of your cabin, but first you have to visit the stream to get some fresh water. What is the distance of the shortest path you can take to complete the trip?

The shortest distance between two points is always a straight line. However, if we want to go to the stream before we go to Grandma’s house, there is NO WAY to travel in a straight line. But what if Grandma’s house was on the OTHER side of the stream? Then we could walk in a straight line (across the stream) directly to Grandma’s house, and this would be the shortest distance. To see that we can still take a path to Grandma’s house that has this same distance, notice that the Red line and the Dotted Red line will be the exact same length! So by using the Pythagorean theorem, we can say that the shortest distance will be the length of the longest side of a right triangle with shorter sides 5 ( = 2 + 3) and 12, which is 13.
