At Funland amusement park, the "Sky Loop" roller coaster seats 24 riders per train. A train departs every 3 minutes, and each ride lasts 2 minutes. The "Splash Splash" water ride seats 12 riders per boat, departs every 4 minutes, and each ride lasts 3 minutes. Both rides start empty at 10:00 AM. How many total riders will have completed at least one ride by 10:12 AM?

Solution
132 riders — First, count completed rides for each attraction by the 12‑minute mark.
**Sky Loop**: Trains leave at 0, 3, 6, 9, 12 minutes. Each ride takes 2 minutes, so only the trains that left at 0, 3, 6, and 9 minutes finish by 12 minutes (0+2, 3+2, 6+2, 9+2). That's 4 trains × 24 riders = 96 riders.
**Splash Splash**: Boats leave at 0, 4, 8, 12 minutes. Each ride takes 3 minutes, so only the boats that left at 0, 4, and 8 minutes finish by 12 minutes (0+3, 4+3, 8+3). That's 3 boats × 12 riders = 36 riders.
Add the two totals: 96 + 36 = 132 riders.
Therefore, the correct answer is the third choice, "132 riders" (index 2).

Math Puzzle: 2026-05-24
A robot factory has two assembly lines, A and B, that each produce a robot and then send it down a straight hallway to the loading dock. The hallway is 120 meters long. Robots from line A walk at 1.5 m/s, while robots from line B ride a conveyor that moves at 2 m/s (the robot itself does not walk). Both lines start producing robots at the same moment, and each line produces a new robot every 30 seconds. However, the conveyor for line B can carry only one robot at a time; a robot must wait at the start of the conveyor until the previous robot has cleared the hallway. After the first robot from each line reaches the dock, the next robot from each line is released immediately (i.e., production continues regardless of travel). How many robots from line A will reach the dock before the third robot from line B reaches the dock?

In a robot factory, three assembly lines work for 4 hours each day.
- Line A builds 5 robots every hour.
- Line B builds 3 robots every hour.
- Line C builds 4 robots every hour.
At the end of each hour, the factory moves 2 robots from Line A’s stock to Line B, and 1 robot from Line B’s stock to Line C. (Robots are only moved; none are created or destroyed by the transfers.)
How many robots are in the factory in total at the end of the 4‑hour shift?

During a classic treasure hunt you discover four stone pedestals, each bearing a single word: LIGHT, BRIGHT, NIGHT, and TREE. A tattered note beside the pedestals reads: "One word is a synonym of another, one word is an antonym of another, and one word rhymes with another." Which pedestal holds the word that does NOT fit any of these three relationships?
