To find Wing's average speed, we use the formula for speed:

$\text{Average speed} = \frac{\text{Distance}}{\text{Time}}$

Given:

• Distance = 80 km
• Time = 2.5 hours

Now, plug the values into the formula:

$\text{Average speed} = \frac{80 \, \text{km}}{2.5 \, \text{hours}} = 32 \, \text{km/h}$

So, Wing's average speed was 32 kilometers per hour (km/h).

Here are 5 related questions:

1. How would the average speed change if the distance was 100 km?
2. What is the formula for speed, distance, and time?
3. If Wing paddled for 4 hours at the same speed, how far would she travel?
4. How long would it take to travel 200 km at this speed?
5. What is the average speed in meters per second (m/s)?

Tip: To convert km/h to m/s, multiply by $\frac{5}{18}$.
