Question

if Francine is able to type 180 words per minute. how many words can she type in 15 second at the same rate​

Answer 1

Answer:

45

Step-by-step explanation:

Let her words per 15 seconds be x.

15 = 60/4

So, x = 180 ÷ 4 = 45

Answer 2

Answer:

45 words

Step-by-step explanation:

180 words/minute

x words/15 seconds

1 minute = 60 seconds

1/4 minute = 15 seconds

180 words/60 seconds

x words/15 seconds

(180 words) × (15 seconds) = (x words) × (60 seconds)

x words = 180 words × 15 seconds

60 seconds

seconds cancel out each other.

then, x words = 180 words × 15/60

x words = 180 words × 1/4

x words = 45 words

Have a nice study time!
