Calculating the Travel Time from St. Petersburg to Moscow

In the 18th century, a journey from St. Petersburg to Moscow took 4 days. Today, a high-speed train covers the same distance in 5 hours and 20 minutes. To calculate how many times faster the journey is now, we can use the following formula:

Speedup factor = (Time taken in the 18th century) / (Time taken today)

Using this formula, we can calculate the speedup factor.

Calculating the Speedup Factor

The speedup factor can be calculated as follows:

Speedup factor = (4 days) / (5 hours 20 minutes)

Converting 4 days to hours: - 4 days = 4 days * 24 hours/day = 96 hours

Now, we can calculate the speedup factor:

Speedup factor = 96 hours / (5 hours + 20 minutes)

Converting 20 minutes to hours: - 20 minutes = 20 minutes / 60 minutes/hour = 0.33 hours

Speedup factor = 96 hours / (5 hours + 0.33 hours) Speedup factor ≈ 96 hours / 5.33 hours Speedup factor ≈ 18

Conclusion

The speedup factor is approximately 18, which means that it is about 18 times faster to travel from St. Petersburg to Moscow today compared to the 18th century.
