According to question
x1 - 1/2 = y1 - 2/3 = z1 - 3/4
Let it be equal to 0
Thus
x1 = 1/2
y1 = 2/3
z1 = 3/4
Similarly
x2 = 2/3
y2 = 1
z2 = 1
Thus distance = root [ x2-x1^2 + y2 - y1^2 + z2 - z1^2 ]
= root [ 1/36 + 1/9 + 1/16 ]
= root [ 29/144 ]
= root 29 / 12
x1 - 1/2 = y1 - 2/3 = z1 - 3/4
Let it be equal to 0
Thus
x1 = 1/2
y1 = 2/3
z1 = 3/4
Similarly
x2 = 2/3
y2 = 1
z2 = 1
Thus distance = root [ x2-x1^2 + y2 - y1^2 + z2 - z1^2 ]
= root [ 1/36 + 1/9 + 1/16 ]
= root [ 29/144 ]
= root 29 / 12
