Question

Larry recorded his time as he ran. What was his average speed from hour 2 to hour 4?



What was his average speed from hour 4 to hour 7?



Did he speed up or slow down?

Answer 1

To calculate Larry's average speed for the specified time intervals, we need the distance he covered during those hours. Unfortunately, you haven't provided any specific distances or times for those hours.

Here's how you can calculate average speed if you have the necessary information:

1. **Average Speed Formula**: Average speed can be calculated using the formula:

\[
\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}
\]

2. **For Hour 2 to Hour 4**:
- Determine the distance Larry covered from hour 2 to hour 4.
- Use the formula above to find the average speed during this time.

3. **For Hour 4 to Hour 7**:
- Similarly, determine the distance covered from hour 4 to hour 7.
- Again, use the average speed formula to calculate his speed for this interval.

4. **Comparison**:
- Compare the average speeds from hour 2 to hour 4 and from hour 4 to hour 7.
- If the average speed during hour 4 to hour 7 is greater than that from hour 2 to hour 4, he sped up. If it is less, he slowed down.

Please provide Larry's running distances for those intervals, and I can help you with the calculations!
