A roaring river of crimson numbers divided the platform. On the far side, a key. On this side, three bridges: one made of prime numbers, one of squares, one of cubes.

A train leaves Paris at 2:00 PM. Another leaves Berlin at 3:30 PM. That’s 1.5 hours later. In that time, the Paris train travels 90 km/h × 1.5 h = 135 km. So the remaining distance when the Berlin train starts is 1050 – 135 = 915 km. Their combined speed is 90 + 120 = 210 km/h. Time to meet after 3:30 PM = 915 ÷ 210 = 4.357 hours. That’s 4 hours and 21.4 minutes. Add to 3:30 PM… sparxmatgs

“The ratio of primes to squares on the safe bridge is 3:2,” said the Curator. “There are 15 primes. How many squares?” A train leaves Paris at 2:00 PM
