Question

Darcy harvests 8 and 3/4 acres of corn every 5/6 hour Darcy harvests corn at a constant rate. how many acres does she harvest per hour

Answer 1

For this case, the first thing we must do is define variables.

We have then:

x: amount of acres of corn harvested

y: number of hours

The corn rate harvested per hour is given by:

$r = \frac{x}{y}$

Substituting values we have:

$r = \frac{8+\frac{3}{4}}{\frac{5}{6}}$

Rewriting we have:

$r = \frac{\frac{35}{4}}{\frac{5}{6}}$

$r = \frac{210}{20}$

$r = \frac{21}{2}$

$r = 10.5 \frac{acres}{hour}$

Answer:

The acre rate of corn harvested per hour is:

$r = 10.5 \frac{acres}{hour}$
