Points O, P and Q are collinear. OP = 3cm, OQ = 11.3cm. Find PQ

It is known from the condition that the points O, P and Q lie on one straight line. OP = 3 cm, OQ = 11.3 cm. And we need to find the length of the segment PQ.

Provided that point O lies in the middle of the segment PQ, it will not be difficult for us to find the length of the segment PQ.

To do this, we must add the lengths of the segments OP and OQ and get:

PQ = OP + OQ = 3 + 11.3 = 14.3 cm.

If point O lies to the left or to the right of the segment PQ, we can find its length as:

PQ = OQ – OP = 11.3 – 3 = 8.3 cm.

Answer: PQ = 14.3 cm (if O is in the middle of the segment), PQ = 8.3 cm (if O is the beginning of the segment).
