Awater sprinkler system can water
1/5
of a yard in
1/10
of a hour. compute the unit rate by setting up a complex fraction and simplifying.
a)
1 yards per hour
b)
2 yards per hour
c)
5 yards per hour
d)
10 yards per hour

Choice B: 2 yards per hour.

Step-by-step explanation:

In order to compute the unit rate we have to divide the number of yards watered by the amount of hours taken:

Take the reciprocal of the denominator of the expression and we get:

Which simplifies to

Thus Unit rate = which is choice B.
