One week before an examination day, a librarian monitored the number of students who visited the library. Then they compared it with the number of visits made in an average week. Approximately 2 x 103 visits were reflected in their logbook during this one-week period, while only about 5 x 102 were reflected on an average week. How many times higher is the number of library visits before examination day compared to the library visits in an average week? Your answer should be a whole number. (1 point)

Answer 1

To determine how many times higher the number of library visits before examination day is compared to the average weekly visits, we need to divide the number of visits during the one-week period by the average number of visits per week.

The number of visits one week before the examination is \( 2 \times 10^3 \) (which is 2000), and the average number of visits per week is \( 5 \times 10^2 \) (which is 500).

Now, we can perform the calculation:

\[ \text{Number of Times Higher} = \frac{2 \times 10^3}{5 \times 10^2} \]

Calculating the fraction:

\[ = \frac{2000}{500} = 4 \]

Thus, the number of library visits before examination day is 4 times higher than the average number of visits in a week.
