2 answers:
Answer:
She can type 225 words in 10 minutes
Step-by-step explanation:
We can find the rate by dividing the number of words by the time
90 words/ 4 minutes
22.5 words per minute
Now to find the number of words in 10 minutes, multiply the rate times the time
22.5 * 10 = 225
She can type 225 words in 10 minutes
Answer:
225 words
Step-by-step explanation:
How many groups of 4 are in 10? 2.5 (4*2.5=10)
So, with this information, you know that you have to multiply 90 2.5 times. This equals 225.
