Answer:
5.5 mm or 15.9 mm.
Explanation:
Given that:
As we know that a segment of a road is formed by placing two points on a road. The distance between two points is the length of the segment. There may be between two points points as well as formation of a shorter period
So in this situation, we have 2 possible cases:
These points can be arranged in two ways only - PRS
PS length will be the total length of the segment so the required length is: PR + RS = 15.9 mm.
The total length of the PR and point S is located between P and R. So the length of PS is: 0.7 - 5.2 = 5.5 mm
Hope it will find you well.
