Test Number of Words Time(minutes)
A. 30. 4
B. 78. 15
C. 99. 22
Answer:
Step-by-step explanation:
To calculate Zane's unit rate/number of words per minute for which each test, we divide number of words in each test by time taken for that test
For test A, unit rate = 30 words/ 4 minutes = 7.5 words per minute
For test B, unit rate = 78 words/15 minutes = 5.2 words per minute
For test C, unit rate = 99 words/22 minutes= 4.5 words per minute
From the above Zane has the highest unit rate in test A and is therefore fastest in test A
