A water 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

Answers

Answer 1
Answer:

Answer:

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:

\therefore Unit\: Rate =(yards)/(hours) =((1)/(5) yards)/((1)/(10)hours).

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

Unit\: Rate=((1)/(5) yards*10)/(hours).

Which simplifies to

(2 yards)/(hour)

Thus Unit rate = (2 yards)/(hour) which is choice B.
