Answer:

120 words in 20 minutes

Step-by-step explanation:

You know that in 5 minutes Brenda can type 30 words.

This means that for us to solve this we have to multiply 5 by 4. This way you get 20.

Then you have to multiply 30 by 4.

This is so that you can figure out how many words she types in 20 minutes rather than 5.

3 x 4=12

using this knowledge we can easily determine,

30 x 4 =120

The answer is 120.

Lanuel

By using direct proportion, Brenda can type 120 words in 20 minutes.

  • Let the first scenario be A.
  • Let the second scenario be B.

Given the following data:

  • Words A = 30 words
  • Time A = 5 minutes
  • Time B = 20 minutes

To find how many words Brenda can type in 20 minutes:

In this exercise, you're required to find how many words Brenda can type while typing the words at the same rate.

By using direct proportion:

30 words = 5 minutes

x words = 20 minutes

Cross-multiplying, we have:

[tex]30[/tex] × [tex]20 = 5x[/tex]

[tex]600 = 5x\\\\x = \frac{600}{5}[/tex]

x = 120 words.

Therefore, Brenda can type 120 words in 20 minutes.
