Question

a researcher read a 12 page article in 30 mintues. on average, how much time did the researcher spend reading each page of the article? (1 minute = 60 seconds)

Answer 1

total minute(one year) = 15 X 365 no of pages read in one year = 12 x 200 = 1200

number of page read in one minute = no of pages read in one year/total minute(one year) = 2400/5475= .4383

ie 1 minute - .4383 page

ie 60 sec - .4383 page

time for 1 page 60/.4383 = 136.89

Part 2

Time needed to read a page 30 sec less

ie 136.89 -30 = 106.89.

so number of pages read in 1 sec = 1/106.89

number of pages read in 1 min = 1/106.89 * 60

number of pages read in a day = 1/106.89 * 60 * 20

number of pages read in a year = 1/106.89 * 60 * 20 * 365 = 4097.67 ( ie 1/106.89 * 7300)

number of books = number of pages read in a year/200 = 20.49
