G 2800 ≤ w ≤ 3500
H 16,800 ≤ w ≤ 21,000
J 4200 ≤ w ≤ 12,000
K 4200 ≤ w ≤ 21,000
Answer by macston(5194)   (Show Source):
You can put this solution on YOUR website! Convert words/min to words/hr
(70 words/min)(60 min/1 hr)=4200 words /hr
If she types 4 hours:
w=(4 Hrs)(4200 words/hr)=16800 words
If she types 5 hours:
w=(5 hrs)(4200 words /hr)=21000 words
Since she types between 4 and 5 hours:
16800 ≤ w ≤ 21000
ANSWER: The correct choice is H, between 16800 and 21000 words per day.
