Leala can write a 500-word essay in an hour. If she writes an essay in 10 minutes, approximately how many words do you think the essay contains? Homework Help ✎

Change hours to minutes.

1 hour = 60 minutes

Use proportions to solve the problem. Assign the variable t to represent the unknown number of words.

$\frac{500\text{ words}}{60\text{ minutes}} = \frac{t\text{ words}}{10\text{ minutes}}$

You can simplify the left side of the proportion and make the denominator 10 by dividing the numerator and denominator by 6. This will also be the answer.

83.33 words (about 83 words)
