Person 'A' left the college at 7 PM at 65% of the original speed. After 30 minutes, he reached the grocery store, picked up a bag of vegetables, and then traveled towards his home. If the time taken to travel from home to the college at regular speed is 2 hours, find the ratio of the distance covered by 'A' from the college to the grocery store to the distance covered by 'A' from the grocery store to his home.
