Yu Yan completes the bike ride in 48 minutes. What is her average biking speed in miles per hour?

To calculate Yu Yan's average biking speed in miles per hour (mph), we need two pieces of information: 

1. The **distance** she biked (in miles).
2. The **time** it took (in hours).

Since we only know the time (48 minutes), we can first convert that to hours:

\[
48 \, \text{minutes} = \frac{48}{60} \, \text{hours} = 0.8 \, \text{hours}.
\]

Next, we use the formula for average speed:

\[
\text{Average speed} = \frac{\text{Distance}}{\text{Time}}.
\]

Since the distance is not provided, please specify the distance she biked, and I will complete the calculation.

Here are some related questions to consider:

1. If Yu Yan biked 10 miles, what would be her average speed?
2. How would the speed change if she completed the ride in 1 hour instead of 48 minutes?
3. If the distance was doubled, how would that affect her average speed?
4. What is the formula to convert minutes into hours in general?
5. How does average speed change if both time and distance increase proportionally?

**Tip**: Always remember to convert time into hours when calculating speed in miles per hour!

Learn how to calculate Yu Yan's average biking speed in miles per hour. Given that the ride took 48 minutes, we'll convert the time to hours and apply the average speed formula. Suitable for students in Grades 5-7. Perfect for understanding unit conversion and speed calculation.
