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

1. Library visits before examination day: \( 2 \times 10^3 = 2000 \)
2. Average weekly visits: \( 5 \times 10^2 = 500 \)

Now we divide the number of visits before the examination by the average weekly visits:

\[ \text{Ratio} = \frac{\text{Visits before exam}}{\text{Average visits}} = \frac{2000}{500} \]

Calculating this gives:

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

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