Answer:
200 items
Step-by-step explanation:
3 mins = 150 items
Let's find the number of items can be sorted in 1 minute:
[tex]\frac3{150} = \frac1x\\\\\\3x = 150\\\\\\x = 150/3\\\\\\x = 50[/tex]
In 1 minute, 50 items can be sorted
To find the number of items in 4 minutes, we multiply it by 4.
[tex]50\cdot4 = 200[/tex]
