Answer 2

jenny can type 1,209 words in 30 minutes how long will it take her to type a 3,000 word essay

 

Step 1

How many words per min?

(1209 words) / (30min)= 40.3 wpm

 

Step 2 

Jenny has 3,000 words so we divide 3,000 words by 40.3wpm

 

(3,000 words)/(40.3 words/min) = 74.45 min   answer

 

74.45 min/60 min/hr = 1.25 hrs = 1 1/4 hrs 

 

1.25 hrs = 1 1/4 hrs  so answer b is the answer
