Answer:
It's about 6,111 kids per second.
Step-by-step explanation:
1 hour = 60 minutes
1 minute = 60 seconds
60*60=3600
1 hour = 3600
hourly rate -> 22,000,000 kids/hr
secondly rate -> 22,000,000/3600 ≈ 6,111
secondly rate -> 6,111 kids/second
Step-by-step explanation:
Since Shanika is standing near the pole, we can safely assume that the triangle formed by Shanika and her shadow is a smaller version of the triangle formed by the pole and its shadow.
By similar triangles:

The height of the pole is 20ft.
In the first problem you are given a formula (y = 3x), along with a table.
From the data in the table, find the slope of the linear equation that relates x and y in that data.
Then compare the two slopes. Which is the greater? the smaller?
