Points a b c are marked on the straight line so that AB = 15 cm, AC = 9 cm. Find the distance between the midpoints of segments AB and AC.

We will solve this task in steps and explain each of them in detail.
1) 15: 2 = 7.5 centimeters – half of the segment AB, since the length of the segment AB is 15 centimeters;
2) 9: 2 = 4.5 centimeters – half of the AC segment, since the length of the AC segment is 9 centimeters;
3) 7.5 – 4.5 = 3 centimeters – the distance between the midpoints of segments AB and AC.
Answer: 3 centimeters.
