a. The average speed while walking is 12 km/h.<br />b. The average speed while bicycling is 30 km/h.<br />c. You travel 18 km/h faster on your bicycle than on foot.

Explicar

## Step 1<br />The problem involves calculating average speed, which is defined as the total distance traveled divided by the total time taken. The formula for average speed is:<br /><br />### **Average Speed = \(\frac{Total Distance}{Total Time}\)**<br /><br />## Step 2<br />For part a, we need to calculate the average speed while walking. The total distance is 5 kilometers and the total time is 25 minutes. However, the time should be in hours for the speed to be in kilometers per hour. Therefore, we convert 25 minutes to hours by dividing by 60 (since 1 hour = 60 minutes).<br /><br />## Step 3<br />For part b, we need to calculate the average speed while bicycling. The total distance is the same (5 kilometers) but the total time is 10 minutes. Again, we convert the time to hours by dividing by 60.<br /><br />## Step 4<br />For part c, we need to find out how much faster you travel on your bicycle than on foot. This is done by subtracting the walking speed from the biking speed.
