Question

if mary types at a constant rate and typed 385 words in 7 minutes, how many words can she type in one minute?

Explanation:

Step1: Identify the given values

We know that in 7 minutes, the number of words typed is 385. Let the number of words typed in 1 minute be \( x \).

Step2: Set up the proportion

Since the typing rate is constant, the ratio of words to minutes should be the same. So we have the proportion \(\frac{385}{7}=\frac{x}{1}\).

Step3: Solve for \( x \)

To find \( x \), we can calculate \( x = \frac{385}{7} \).
Calculating \(\frac{385}{7}=55\).

Answer:

55
