Question

1. jenny can send texts on her phone at the rate of 32 words per minute. if she sends 8 texts that average 80 words each, about how long would it take her?

proportion with units
__ = __
work + solution

Explanation:

Step1: Find total words in 8 texts

Each text has 80 words, so 8 texts have \( 8 \times 80 = 640 \) words.

Step2: Use rate to find time

Rate is 32 words per minute. Let \( t \) be time in minutes. Then \( \frac{32 \text{ words}}{1 \text{ minute}} = \frac{640 \text{ words}}{t \text{ minutes}} \). Cross - multiply: \( 32t = 640 \).

Step3: Solve for t

Divide both sides by 32: \( t=\frac{640}{32}=20 \).

Answer:

It would take her 20 minutes.
