An ant is on one side of a branch and a fly is on the other side of the branch. Puzzle Image For a change of scenery, they decide to swap places. So the ant crawls along the branch from A to B and the fly crawls along the branch from B to A. They each travel in a perfectly horizontal line. After they pass each other, it takes the ant 20 seconds to reach point B, while it takes the fly only 5 seconds to reach point A. How much time did it take each insect to make the journey?

Do you have a suggestion for this puzzle (e.g. something that should be mentioned/clarified in the question or solution, bug, typo, etc.)?
