1/4 5/8 = 1 x 8 5 = 4 1 x 8 20 = x
Unit Rate: 8 20 square feet per hour
** the unit rate is:**
r = 8 20 h f t 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 = 4 1 8 5
Then, rewriting the unit rate we have:
r = 8 ∗ 1 4 ∗ 5
r = 8 20
To find the unit rate of a fertilizer covering area, divide the area by time. This results in a unit rate of 2 5 square feet per hour, or 2.5 square feet per hour. Therefore, the fertilizer covers 2.5 square feet in one hour.
