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

Question

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 how many times higher the number of library visits before examination day is compared to the average number of visits, we can divide the number of visits during the examination week by the number of visits in an average week.

Given:

• Visits during examination week = \( 2 \times 10^3 = 2000 \)
• Average visits per week = \( 5 \times 10^2 = 500 \)

Now, we perform the division:

\[ \text{Times higher} = \frac{\text{Visits during examination week}}{\text{Average visits per week}} = \frac{2000}{500} \]

Calculating this:

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

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