The answer would be 2 inches.
The ratio of the model to the real figure is 1 feet to 12 feet, since 15 divided by 1.25 is 12. And since 24 inches = 2 feet, 2 divided by 12 would equal 1/6 feet, which would equals 2 inches.

Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls
= 14
