The tables show the books read by two different students. Explain how to determine which student read faster.

The first student read faster than the second student.

Step-by-step explanation:

Step 1:

To determine how long each student takes to read a book, we divide the time taken to read by the number of books read in that period.

Time taken to read a book = .

In the given table, the second column values are times taken to read and the first column represents the number of books read in that period.

Step 2:

For the first student, the time taken is calculated.

The first student's time taken to read a book = = = 10 minutes to read a book.

Step 3:

Similarly, the time taken to read a book is calculated for the second student.

The first student's time taken to read a book = = 12 minutes to read a book.

Step 4:

Now we compare the times taken. The first student read a book in 10 minutes while the second student took 12 minutes for a book. So the first student read faster.
