Andriy, Bogdan and Olesia were walking by the same road from home to the school. Andriy was walking with velocity equal to $a$ km/h for $(2-b)$ hours, Bogdan was walking with velocity equal to $b$ km/h for $(2-c)$ hours, Olesia was walking with velocity equal to $c$ km/h for $(2-a)$ hours, where $a, b, c$ are some real numbers. What is the distance between home and school if it is known that it is equal to an integer number?
