Introduction
In this article, we will compare the bike ride speeds of two individuals, Julia and Katie. Julia can finish a 20-mile bike ride in 1.2 hours, while Katie can complete the same ride in 1.6 hours. We will calculate the difference in their riding speeds and determine by how many miles per hour Julia's speed exceeds Katie's.
Calculating Riding Speed
To calculate the riding speed of Julia and Katie, we need to use the formula:
Riding Speed (mph) = Distance (mi) / Time (hours)
We can apply this formula to both Julia and Katie's data.
Julia's Riding Speed
- Distance (mi) = 20 miles
- Time (hours) = 1.2 hours
Riding Speed (mph) = 20 miles / 1.2 hours = 16.67 mph
Katie's Riding Speed
- Distance (mi) = 20 miles
- Time (hours) = 1.6 hours
Riding Speed (mph) = 20 miles / 1.6 hours = 12.5 mph
Comparing Riding Speeds
Now that we have calculated the riding speeds of Julia and Katie, we can compare them to determine by how many miles per hour Julia's speed exceeds Katie's.
Speed Difference (mph) = Julia's Speed (mph) - Katie's Speed (mph) = 16.67 mph - 12.5 mph = 4.17 mph
Therefore, Julia's riding speed exceeds Katie's by 4.17 miles per hour.
Conclusion
In conclusion, Julia's riding speed is significantly higher than Katie's. By calculating their riding speeds and comparing them, we found that Julia's speed exceeds Katie's by 4.17 miles per hour. This highlights the importance of considering individual differences in speed when comparing performance in physical activities like bike riding.
