Amy is on holiday enjoying some winter sunshine and has been using trams to travel around.
Trams to the airport leave every 50 minutes.
Trams to the beach leave every 35 minutes.
A tram to the airport and a tram to the beach leave together at 9:30am.
When is the next time that a tram to the airport and a tram to the beach will leave together?
Answer:
The Trams to the airport will leave at 10:20, 11:10, 12:00, 12:50, 13:40, 14:30 and 15: 20
The Trams to the beach will leave at 10:05, 10:40, 11:15, 11:50, 12:25, 13:00, 13:35, 14:10, 14:45 and 15:20
So, the next time they meet is 15:20pm.
