Question

a teacher takes 2 hours and 20 minutes to mark twenty literacy test papers. what is the mean time spent on each paper? give your answer in minutes​

Answer 1

The teacher takes a total of 2 hours and 20 minutes to mark twenty literacy test papers. To find the mean time spent on each paper, we need to divide the total time by the number of papers. The mean time spent on each paper is 7 minutes.

Answer 2

To find the mean time spent on each paper, you can divide the total time by the number of papers:

Total time = 2 hours and 20 minutes = 2 hours + 20 minutes

Now, convert the hours to minutes because there are 60 minutes in an hour:

2 hours = 2 * 60 minutes = 120 minutes

Now, add the 20 minutes:

Total time = 120 minutes + 20 minutes = 140 minutes

Next, divide the total time by the number of papers:

Mean time per paper = Total time / Number of papers

Mean time per paper = 140 minutes / 20 papers

Mean time per paper = 7 minutes

So, the mean time spent on each paper is 7 minutes.
