undefined To find the average running rate, follow these steps:

1. **Understand the formula**: Average rate = Total distance ÷ Total time.

2. **Identify the distance**: The sprinter runs 100 meters.

3. **Identify the time**: The sprinter takes 11.5 seconds.

4. **Plug in the numbers**:
   - Average rate = 100 meters ÷ 11.5 seconds.

5. **Calculate**: 
   - Average rate = 8.69565217391304 meters per second.

6. **Round it off**: About 8.7 meters per second.

So, the average running rate is about **8.7 meters per second**.

Sebastian Acosta · Answer

Average speed is equal to distance divided by time.

#v_(av) = (Delta d) / (Delta t)# Plug these values into your formula, then into your calculator - should give you an average speed of 8.7 #m/(s^2)#

William Audy · Answer

undefined To find the average running rate, divide the distance by the time:

Average running rate = Distance / Time

Average running rate = 100 meters / 11.5 seconds = 8.69565217 meters per second (approximately 8.7 m/s).
