Question

Can you find the unit rate? A fertilizer covers 5/8 square foot in 1/4 hour. What is the unit rate?

Answer 1

For this case we must know the unit rate.

To do this, we divide the amount of area covered by the fertilizer, between time.

We have then:

$r =\frac{\frac{5}{8}}{\frac{1}{4}}$

Then, rewriting the unit rate we have:

$r =\frac{4*5}{8*1}$

$r =\frac{20}{8}$

Answer:

the unit rate is:

$r =\frac{20}{8}\frac{ft^2}{h}$

Answer 2

$\frac{5/8}{1/4} = \frac{x}{1} \\ \\ \frac{5}{8}= \frac{1}{4} x \\ \\ \frac{20}{8} =x$

Unit Rate: $\frac{20}{8}$ square feet per hour
