#### Problem 2: Message Length
Question: The average length of a text message is 100 characters. Estimate the number of characters exchanged in a week by a person who sends 20 text messages per day.

Solution:
1. Calculate the total number of text messages sent in a week:
\[
\text{Text messages per week} = \text{Text messages per day} \times 7
\]
\[

2. Determine how many 10-minute intervals are in 60 minutes:
\[
\text{Number of 10-minute intervals} = \frac{60}{10} = 6
\]
3. Calculate the total data usage:
\[
\text{Total data usage} = \text{Data per 10 minutes} \times \text{Number of intervals}
\]
\[
\text{Total data usage} = 5 \times 6 = 30 \text{ MB}
\]

Answer:
\[
\boxed{30}
