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?

Answer 1

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.
