Given :
A point x whose distance from A is 5 1/3 units.
distance between x and B is 2/3 units.
To Find :
Distance between A and B if they both are on left side of straight line from x.
Solution :
Let distance between A and B is d :
[tex]d=|A-B|\\\\d=|5\dfrac{1}{3}-\dfrac{2}{3}|\\\\d=|\dfrac{16}{3}-\dfrac{2}{3}|\\\\d=\dfrac{14}{3}\\\\d=4\dfrac{2}{3}\ units[/tex]
Therefore, distance between A and B is 4 2/3 units.
Hence, this is the required solution.
