You read 50 pages in an hour your sister reads 40 pages in an hour how many more pages did you read than your sister reads in 1/2 hour

To start to figure this problem out, we can first figure out how many more pages you read in an hour compared to your sister.

50 - 40 = 10, so you read 10 more pages in 1 hour.

Now we have to figure out how much more you would read in 1/2 an hour. Since 1/2 an hour is 1/2 of an hour, we can divide 10 by 2 to figure out how many more pages you read in an hour compared to your sister. 10 divided by 2 is 5, so you read 5 more pages every half hour.
