Question

Johanna can type 120 words in 3 minutes. Using the same unit rate, how many words can

Answer 1

Answer:

600 words.

Step-by-step explanation:

If Johanna can type 120 words in 3 minutes, and the problem is asking us to find how many words she can type in 10 minutes at the same unit rate, we'll have to start by solving how many words she can type in 1 minute:

$\frac{120}{3}$

Dividing 120 words into 3:

$=60$ words per minute.

Now that we know how many words Johanna types in one minute (per minute), we can multiply the words per minute by 10 (minutes):

$60$ × $10=600$ words in 10 minutes.

We can check our work by dividing 600 words into 10 minutes to see if we achieve the same unit rate of 60 words per minute:

$\frac{600}{10}$

$=60$ words per minute.

Since we have the same unit rate, our answer is correct!
