Answer:
You can break 24 things
Explanation:
One minute is 60 seconds, so all you have to do is double how many things you can break in 30 seconds
x = 24
We can use a ratio to solve
30 seconds 60 seconds
------------------ = --------------
12 things x things
Using cross products
30x = 60 * 12
Divide by 30
30x/30 = 60 * 12/30
