The actual distance between Yappy city and Quiet city when it is 23 cm in map is 9.2 miles.
What is scaling ?
It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.
It is given that :
The distance on the map between Yappy city and Quiet city is 23 cm
and,
5cm = 2 miles
now, for 1 cm on map it is equal to 2/5 miles of actual distance.
Therefore to find the actual distance of 23 cm in map we simply multiply 23 with 2/5 :
actual distance :
2/5 x 23 = 9.2 miles
Therefore, the actual distance between Yappy city and Quiet city is 9.2 miles.

Answer:
The age of each triplet if 6 years.
Step-by-step explanation:
Let us assume the age of first child in triplet = m years
Since, the children are triplet, so age of 3 children are SAME.
⇒The age of second child in triplet = m years
and, The age of third child in triplet = m years
Also, the age of fourth children = 13 years
So, sum of age of all four children =
Sum of age of all triplets + Age of fourth child = m + m + m + 13 = 3 m + 13
Given: The sum of the ages of their children is 31.
⇒ 3 m + 13 = 31
or, 3 m = 31 -1 3 = 18
or, m = 18/3 = 6
or, m = 6 years
Hence the age of each triplet if 6 years.
