Brilliant's physics problems this week are all about the hyperloop, a new high-speed transportation system proposed by inventor Elon Musk. The hyperloop is a tube through which capsules move at a top speed of 1,220 kilometers per hour (760 miles per hour). Our problems explore some of the technical challenges it faces as well as the benefits it provides. – Kayu Kaou · 3 years, 7 months ago

Since 24 = 8 * 3, the sum of the digits must be = 0 (mod 3), which is satisfied by the fact that the sum of the digits must be 24. Therefore, we ignore this condition, so now we need the smallest n = 0 (mod 8 ), whose sum of digits = 24. We clearly – Kayu Kaou · 3 years, 7 months ago
