Question

Kayla can type 27 words in one minute. Cooper says he can type faster. When given 45 seconds to type, Cooper can types 26 words. Who is faster? How do you know? How many words could each of them type in 1 ¼ hours?
Claim (What is the answer to the question presented?):


Evidence (Show your drawing and/or algorithms) (You may also post a picture of your work): 27 words:1 minute 26 words: 45 seconds = 26 words: 0.75 minutes = 26/0.75 = 35 words : 1 minute


Reasoning (Explain your thinking):

Answer 1

Step-by-step explanation:

Kayla's typing speed per minute is 27 words

Cooper's typing speed per minute is 35 words

Now 1*1/4 hours = 1 hour 15 minutes = 75 minutes

Thus Kayla can type 75*27 = 2025 words in 75 minutes

Whereas Cooper can type 75*35 = 2625 words in 75 minutes

Thus Cooper types 600 more words than Kayla in 75 minutes

Hence we can say Cooper types faster!!!
