Problem 1:
A factory produces 200 reams of paper daily. Calculate the total reams of paper produced in 15 days.
#### Solution:
To solve this problem, we need to calculate the total production of paper over 15 days. The factory produces
200 reams of paper per day, and we are asked to find the total for
15 days.
The formula for total production is:
\[
\text{Total Production} = \text{Daily Production} \times \text{Number of Days}
\]
Substitute the given values:
\[
\text{Total Production} = 200 \, \text{reams/day} \times 15 \, \text{days}
\]
Perform the multiplication:
\[
200 \times 15 = 3000
\]
Thus, the total reams of paper produced in 15 days is:
\[
\boxed{3000}
\]

Problem 2:
The Heathrow Airport, London receives 7926 passengers every hour. Find the total number of passengers received in 5 hours.
#### Solution:
To solve this problem, we need to calculate the total number of passengers received over 5 hours. The airport receives
7926 passengers per hour, and we are asked to find the total for
5 hours.
The formula for total passengers is:
\[
\text{Total Passengers} = \text{Passengers per Hour} \times \text{Number of Hours}
\]
Substitute the given values:
\[
\text{Total Passengers} = 7926 \, \text{passengers/hour} \times 5 \, \text{hours}
\]
Perform the multiplication:
\[
7926 \times 5 = 39630
\]
Thus, the total number of passengers received in 5 hours is:
\[
\boxed{39630}
\]
---
Final Answers:
1. Total reams of paper produced in 15 days: \(\boxed{3000}\)
2. Total number of passengers received in 5 hours: \(\boxed{39630}\)
