Ответ:
Mass of Cocker Spaniel = 20.49 kg - 7.59 kg = 12.9 kg
From this calculated mass, we determine the mass of the Newfoundland,
Mass of Newfoundland = 12.9 kg + 52.656 kg = 65.556 kg
The difference of the weights of Newfoundland and Springer Spaniel,
D = 65.556 kg - 20.49 kg = 45.066 kg
ANSWER: 45.066 kg
