Question

Two Formula 1 cars leave the starting line at the same time. One car takes 280 seconds to complete one lap ad the other takes 288 seconds. How long after the start will it take for them to meet again at the starting line?

Answer 1

280(n+1) = 288 (n)

280 = 8 n

n = 35

288 * 35 = 10080 seconds or 2.8 hours
