Three individuals—Aman, Bittu, and Raju—each complete a distance of 120 meters in different time durations: 'x' seconds for Aman, 'x - 2' seconds for Bittu, and 'x + 3' seconds for Raju. Additionally, the ratio of Aman's speed to Raju's speed is given as 5:4. Quantity I: If Bittu and Raju compete in a 300-meter race, how much distance will separate them when the winner crosses the finish line? Quantity II: If Aman and Raju compete in a 320-meter race, how much distance will separate them when the winner crosses the finish line?
