Question

At an aquarium, a tour of the shark tanks begins every 45 minutes. The dolphin show begins every 30 minutes. If the shark tour and the dolphin show both start at 9am, at what time will they start at the same time again? Explain your answer

Answer 1

The answer would be 10:30. This would be because the fourth dolphin show would be at 10:30 and then the shark would start at 10:30

Answer 2

10:30 cause the the fourth dolphin show is 10:30 and third shark tank tour starts at 10:30

Hope this helps
