difference between words in a minute

200- 160 = 40

difference multiplied by 60 to make it difference in hours

40 * 60 = 2400

difference in hours multiplied by 14 to see the total

14 * 2400 = 33600

divide by 160

= 210

divide by 60

= 3.5

14 + 3.5

=17.5 hours

If Maria reads 200 words per minute then there are 14 hrs * 60 min/hr * 200 words/min = 168,000 words in the book.

If Linda can read 160 words per minute then she will need 168,000 words/160 word per min = 1050 minutes to read the book which is 17 1/2 hours.

If Maria can read 200 words a minute she can read 12000 an hour and over 14 hours will read 168000 words

Linda can read 160 a minute which is 9600 an hour. In total she will need 168000/9600 hours to read the book, Linda will need 17.5 hours

5min=1,000 words

10min= 2,000 words

20min=4,000 words

40min= 8,000 words

50min= 10,000 words

1hr= 12,000 x 14 = 168000 words

5min = 800

10min= 1600

20min= 3,200

40min= 6,400

50min= 8,000

1hr= 9,600

therefore itll take 17.5 hrs for linda to finish the book.

17.5 hours

200words/minute x 60min/hour x 14 hours= 168,000 words total in the book

168,000 words / 60 min/hour / 160 words/min= 17.5 hours
