document.write( "Whenever twins Sandra and Rachel read a book, Sandra wastes no time and begins to read immediately at a constant rate of 3 pages per minute, while Rachel has a certain “ritual” that she always performs: Pour a glass of milk, get her favorite pillow, solve a math problem and then begin to read. This process of Rachel’s takes 10 minutes, but she can read at a rate of 5 pages per minute. If they begin their perspective reading procedures at 8:00 pm, then at what time will they have both read the same number of pages? \n" );
