It is always a very bad idea to have blanks in directory and file names, as they cause confusion.
So I suggest you rename the directory in the Finder (you use a Mac, right?) to 301_Assignment, and use a name of A1.rtf for the file, making the ODS statement look like this:
ods rtf file="/folders/myfolders/301_Assignment/A1.rtf";
Also take care of the spelling and capitalization, both OSX and the Linux in the University Edition virtual machine are case sensitive.
The Mac path (/Users/.....) is not visible in the virtual machine; you can only use /folders/myfolders or a subdirectory there.
