Archbridge Bus Company have a very small road on the exit of their bus garage. This means they need to be aware of when this roa
d will be used by multiple buses. The 157 bus leaves every 33 minutes. The 183 bus leaves every 6 minutes. All buses start service at 9:00. Apart from when the buses leave at 9:00, at what time will both be leaving the garage at the same time?
