Question

On a number line, points U, V and A are such that d(U, A) = 215 units, d(V, A) = 140 units and d(U, V) = 75 units. Which of the points is between the other two?

• A. Point U is between the points V and A.
• B. Point V is between the points U and A.
• C. Point A is between the points U and V.
• D. None of the above

Answer 1

The correct option is B Point V is between the points U and A.

Given, d(U, A) = 215 units
d(V, A) = 140 units
d(U,V) = 75 units

d(U, A) = 215

and d(U, V) + d(V, A) = 75 + 140 = 215

$\therefore$ d(U,A) = d(U, V) + d(V, A)

Hence, point V is between the points U and A.
