it took heather 2/3 of an hour to read 20 pages in her library book. how long did it take her to read one page

NNADVOKAT [17]

2/3 hour . 1 hour = 60 minutes.

2/3 hour = (2/3) * 60

= 40 minutes.

20 pages took (2/3) hour = 40 minutes.

20 pages took her 40 minutes to read.

1 page = 40/20 = 2 minutes.

1 page took her 2 minutes to read.
