I have been trying to get this question out but I really have no idea...

The rise and fall in a sea level due to tides can be modelled by simple harmonic motion. On a certain day, a channel is 10 metres deep at 9am when it is low tide, and 16 metres deep at 4pm when it is high tide. If a ship needs 12 mteres of water to sail down a channel safely, at what times (correct to the nearest minute) between 9am and 9pm can the ship pass through?

If someone could help me out with this I would be eternally grateful

Thanks,
