Lin can type 192 words in 6 minutes. Hoi can type 112 words in 4 minutes. Which statement is true?
Answers
Answer:
B. Lin can type 4 more words per minute than Hoi.
Step-by-step explanation:
We have been given that Lin can type 192 words in 6 minutes. Hoi can type 112 words in 4 minutes.
First of all, we will find per minute typing speed of Lin and Hoi as:
\text{Typing speed of Lin}=\frac{192\text{ words}}{\text{6 minutes}}
\text{Typing speed of Lin}=32\frac{\text{ words}}{\text{ minutes}}
Therefore, Lin's typing speed is 32 words per minute.
\text{Typing speed of Hoi}=\frac{112\text{ words}}{\text{4 minutes}}
\text{Typing speed of Hoi}=28\frac{\text{ words}}{\text{ minutes}}
Therefore, Hoi's typing speed is 28 words per minute.
We can see that Lin's typing speed is 4 more (32-28) words per minute more than Hoi, therefore, option B is the correct choice.
