c# Repository with Two Data Providers

I am creating one repository and I have to deal with two data providers(IFileDataAccess, IDbDataAccess) to build my model object(MyModel).

I have written below code, but I feel it's not correct, it's important to have MyModel class with all written properties as they all be used together.

Please suggest a good way to achieve this.

Thanks!

class MyModel
    {
    public Schedule Schedule { get; set; }
    public Rates Rates { get; set; }
    public Balance Balance { get; set; }
    }

class MyRepository 
{
    private IFileDataAccess  _fileDataAccess;
    private IDbDataAccess  _dbDataAccess;

    public MyClass (IFileDataAccess fileDataAccess, IDbDataAccess dbDataAccess)
    {
        _fileDataAccess= fileDataAccess;
        _dbDataAccess=dbDataAccess;
    }

    public MyModel GetMyModel()
{
    return new MyModel(){Schedule=_dbDataAccess.GetSchedule(),Rates=_fileDataAccess.GetRates(), Balance=_fileDataAccess.GetBalance()};
}

}
