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

`(5/8)/(1/4) = (x)/(1) \\ \\ (5)/(8)= (1)/(4) x \\ \\ (20)/(8) =x`

Unit Rate:
`(20)/(8)` square feet per hour

Answer 2

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 =((5)/(8))/((1)/(4))`

Then, rewriting the unit rate we have:

`r =(4*5)/(8*1)`

`r =(20)/(8)`

Answer:

the unit rate is:

`r =(20)/(8)(ft^2)/(h)`
