Question

Can someone anyone please help me with this question???

Answer 1

We see that we have conversion rates of $\frac{12}{3} = 4$ photos per minute, and thus $\frac{1}{4} = 0.25$ minutes per photo.  I'll abbreviate photos as $p$ and minutes as $m$.  We have:

$4 m \cdot \frac{4 p}{1 m} = 16 p$

$24 p \cdot \frac{1 m}{4 p} = 6 m$

$9 m \cdot \frac{4 p}{1 m} = 36 p$

$40 p \cdot \frac{1 m}{4 p} = 10 m$
