Since the segments are given by BО and ОC, the point О is common for the segments.
There are two options for the location of points on the same straight line.
In the first case, point O lies between points B and C, then the segment BC = BО + OC = 17 + 25 = 42 cm.
In the second case, point B, since the segment BО is less than OC, lies between points C and O, then the segment BC = OC – BО = 25 –17 = 8 cm.
Answer: Sun distance can be 8cm or 42cm.
