Question

Nina can type 128 words in 4 minutes. At this rate, how many words can Nina type in an hour.

Answer 1

1920

Explanation:

We know that it takes her 4 minutes to type 128 words

So we need to figure out how many it takes her to type a word per minute

128 divided by 4=32

So multiply 32 word by 60 ( 60 mins = an hour)

Answer=1920

Answer 2

1,920 words

Explanation:

60 divided by 4 is 15

15 times 128 is 1,920.
