2 blocks = 1 minute
18 blocks = 9 minutes
60 blocks = 30 minutes
She already ran for 9 minutes. She needs to run 42 more blocks.
If we subtract 9 minutes from 30 minutes, we get 21 minutes. Therefore, she needs to run 21 more minutes.
To verify this, we check the proportionality.
2 blocks = 1 minute
42 blocks = 21 minutes
42 blocks / 21 minutes = 2 blocks per minute
Hope this helps!

Answer:
20 children.
Step-by-step explanation:
We can solve this using an equation or simple mental math:
The equation: x=children x+20=adults
x + (x+20) = 60
2x + 20 = 60
2x = 40
x = 20
Mental Math: 40 plus 20 is 60 and 40 is 20 more than 20 so there are 40 adults and 20 children.
