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 2×10^3 visits were reflected in their logbook during this one-week period, while only about 5×10^2 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.

Answer 1

To find out how many times higher the number of library visits before examination day is compared to the average weekly visits, we can perform the following calculation:

1. Identify the number of visits before examination day: \( 2 \times 10^3 = 2000 \) visits.

2. Identify the number of average weekly visits: \( 5 \times 10^2 = 500 \) visits.

3. Now, divide the number of visits before examination day by the number of average weekly visits: \[ \text{Number of times higher} = \frac{2000}{500}. \]

4. Simplifying the division: \[ \frac{2000}{500} = 4. \]

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