Paul can type 60 words per minute and Jennifer can type 80 words per minute. How does Paul's typing speed compare to Jennifer's?

A. Paul can type 1 /3 as fast as Jennifer.
B. Paul can type 3 /4 as fast as Jennifer.
C. Paul can type 1 /4 as fast as Jennifer.
D. Paul can type 11 /3 times as fast as Jennifer.

Respuesta :

Let's first make their times into a fraction of Paul's words per minute over Jennifer's words per minute and then reduce it. 60/80 = 20(3)/20(4) = 3/4. Paul types 3/4 as fast as Jennifer, so the answer is B. Paul can type 3 /4 as fast as Jennifer.
