At 'Adventureland' amusement park, the 'G-Force Tower' is 3 km from the main entrance. Leo starts walking directly towards it at a constant speed of 6 km/h. Mia also starts from the entrance at the same time. She walks 1 km towards the tower at 4 km/h, then stops for 15 minutes at a gift shop, and finally walks the remaining 2 km to the tower at a brisk pace of 8 km/h. Who arrives at the G-Force Tower first?

Solution
Leo arrives first. — To solve this, we need to calculate the total travel time for both Leo and Mia.
For Leo:
Distance = 3 km
Speed = 6 km/h
Time = Distance / Speed = 3 km / 6 km/h = 0.5 hours. (Which is 30 minutes)
For Mia:
Mia's journey has three parts:
1. Walking the first 1 km:
Distance = 1 km
Speed = 4 km/h
Time1 = 1 km / 4 km/h = 0.25 hours (or 15 minutes)
2. Stopping at the gift shop:
Time2 = 15 minutes = 0.25 hours
3. Walking the remaining 2 km:
Distance = 2 km
Speed = 8 km/h
Time3 = 2 km / 8 km/h = 0.25 hours (or 15 minutes)
Total time for Mia = Time1 + Time2 + Time3 = 0.25 hours + 0.25 hours + 0.25 hours = 0.75 hours. (Which is 45 minutes)
Comparing their total times:
Leo's time = 30 minutes
Mia's time = 45 minutes
Leo arrives at the G-Force Tower significantly earlier than Mia.

Math Puzzle: 2026-04-29
An alien civilization sends out a fleet of 7 identical explorer ships to scan for habitable planets. Each ship is assigned to scan a different sector of the galaxy. After completing its scan, each ship reports the number of habitable planets it found. The first ship reports finding 3 habitable planets, the second reports 4, the third reports 5, and so on, with each subsequent ship reporting one more habitable planet than the previous one. However, due to overlapping sectors, it is later discovered that for every ship (from the second ship onwards), exactly one of the planets it found was *already found by the very first ship*. All other planets found by any ship were unique to that ship's specific discoveries (apart from the single overlap with the first ship). How many *unique* habitable planets were found in total across all 7 ships?

The ancient civilization of Xylos, fascinated by cosmic order, used precise geometric patterns in their sacred artifacts. One such artifact, 'The Stellar Hexagon', was constructed using exactly seven glowing crystals. These crystals were arranged on a flat surface to form a perfect, large hexagon: one crystal at the very center, and the remaining six crystals forming a regular hexagonal ring around it, all equidistant from the center and from their immediate neighbors in the ring. If an explorer is tasked with identifying all distinct equilateral triangles formed by connecting any three of these seven crystals, how many such triangles would they find?

An astronaut, Dr. Aris Thorne, is alone in orbit around a newly discovered exoplanet, designated Kepler-186f. Using the ship's most advanced optical telescope, he observes what appears to be a large, perfectly rectangular structure on the planet's surface. It seems to be slowly but consistently traversing the rugged alien landscape. This is perplexing, as no probes have ever landed there, and the planet is believed to be uninhabited. What is the most logical explanation for what Dr. Thorne is observing?
