Darcy harvest 8 3/4 acres of corn every 5/6 of an hour. How many acres per hour?
otez555 [7]

Answer:

The answer is 10\frac{1}{2}\ per\ hour.

Step-by-step explanation:

Given:

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour.

Now, to find the acres per hour it takes to harvest.

Darcy harvest = 8\frac{3}{4}=\frac{35}{4}\ acres.

The time he took to harvest = \frac{5}{6}\ hour.

So, to get the acres per hour we put formula:

Distance = \frac{35}{4}\ acres.

Time=\frac{5}{6}\ hour.

Speed=\frac{distance}{time}

Speed=\frac{\frac{35}{4}}{\frac{5}{6}}

Speed=\frac{35}{4}\times \frac{6}{5}

Speed=\frac{210}{20}

Speed=\frac{21}{2}

Speed=10\frac{1}{2}\ per\ hour.

Therefore, the answer is 10\frac{1}{2}\ per\ hour.
