Question

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 determine how many times higher the number of library visits during the week before the examination is compared to the average week, we can set up the following calculation:

1. The number of visits during the examination week: \(2 \times 10^3 = 2000\) visits.
2. The number of visits during an average week: \(5 \times 10^2 = 500\) visits.

Now, we divide the number of visits during the examination week by the number of visits during an average week:

\[
\text{Ratio} = \frac{2000}{500}
\]

Calculating this gives:

\[
\text{Ratio} = 4
\]

Thus, the number of library visits before the examination day is **4 times** higher compared to the average week.
