Two trains arrived at a station at 2:55 P.M., with one arriving on Track A, and the other arriving on Track B. Trains arrive on Track A every 16 minutes, and they arrive on Track B every 18 minutes. At what time will trains next arrive at the same time on both tracks?

???

LCM(16,18) = 2^4 * 3^2 = 144 minutes or 2:24 hours
