The Brown Office Rental Company has purchased a new computer for the secretary to use for customer requests. She can type 70 wor
ds per minute, on the average. If she types 4 to 5 hours per day, she will average how many words, w, per day? F 16,800 ≤ w ≤ 60,000
G 2800 ≤ w ≤ 3500
H 16,800 ≤ w ≤ 21,000
J 4200 ≤ w ≤ 12,000
K 4200 ≤ w ≤ 21,000
First you want to find how many words she types per hour. There are 60 minutes in 1 hour. So multiply 70 words/min times 60 min/ 1 hr to cancel out the minutes. You will get 4200 words / hr Then multiply 4200 by 4 and 5 use * as multiplication symbol 4200 words/hr * 4 = 16,800 words/hr 4200 words/hr * 5 = 21,000 words/hr She will type 16,800 - 21,000 words/hr
