we know P and Q are midpoints, so if we shift P on A, Q will come on C..
between A and C, there are 6 gaps of 3/7..
E

Point P is => $$\frac{1}{2}(\frac{9}{7}+\frac{12}{7})=\frac{21}{14}$$

Point Q is =>$$\frac{1}{2}(\frac{6}{7}+\frac{9}{7})=\frac{15}{14}$$

Total distance between P->Q = Distance from P to 0+ Distance from Q to 0
=>$$\frac{21}{14}+\frac{15}{14}=\frac{18}{7}$$
