Answer:
smaller distance = 108 Km
Explanation:
given the ratio of distances = 15 : 9
the 15 part of the ratio refers to the larger distance of 180 Km , then
dividing the distance by the part of the ratio gives the value of 1 part of the ratio.
180 Km ÷ 15 = 12 Km
the smaller distance = 9 × 12 Km = 108 Km
