What are the coordinates of point B on Line AC such that AB is 3 times as long as BC? (Screenshots supplied to clarify)

I know that the length of BC is \(\frac{2\sqrt{10}}{3}\) : in decimal form is 2.10818510… but it is hard to find the cordinate

The length of  AC = sqrt( 62 + 22 ) = 6.32455532

 

The length of  BC = AC / 4 = 1.58113883

 

The coordinates of point B =>   B (3.5, 0.5)  indecision
