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 2×103 visits were reflected in their logbook during this one-week period, while only about 5×102 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 find out how many times higher the number of library visits before examination day is compared to the average weekly visits, we can use the following formula:

\[ \text{Times higher} = \frac{\text{Visits before examination day}}{\text{Average weekly visits}} \]

From the information given:

• Visits before the examination day: \(2 \times 10^3 = 2000\)
• Average weekly visits: \(5 \times 10^2 = 500\)

Now, substituting the values into the formula:

\[ \text{Times higher} = \frac{2000}{500} \]

Calculating this gives:

\[ \text{Times higher} = 4 \]

Therefore, the number of library visits before examination day is 4 times higher compared to the library visits in an average week.
