Answer:
The unit rate is 2 yards per hour.
Step-by-step explanation:
A water sprinkler system can water 1/5 of a yard in 1/10 of a hour.
A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
To find the unit rate of water per hour, divide the number of water by number of hours:
[tex]\dfrac{1}{5}:\dfrac{1}{10}=\dfrac{1}{5}\cdot \dfrac{10}{1}=2[/tex]
The unit rate is 2 yards per hour.
