Answer:

Charles completed the quiz problems at the slowest rate

Step-by-step explanation:

$\frac{15}{10}=1.5\ quiz\ problems\ per\ minute$

2) Andrew completed 12 quiz problems in 8 minutes

$\frac{12}{8}=1.5\ quiz\ problems\ per\ minute$

3) Charles completed 16 quiz problems in 16 minutes

$\frac{16}{16}=1\ quiz\ problem\ per\ minute$

Compare the unit rates

1 < 1.5

therefore

Charles completed the quiz problems at the slowest rate
