To calculate the average speed for the entire trip, we'll use the formula:

$\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}$

Step 1: Calculate the Total Distance

From the earlier calculation:

• First Segment: 36 km
• Second Segment: 23.75 km
• Third Segment: 35.87 km

Total distance: $\text{Total Distance} = 36 \, \text{km} + 23.75 \, \text{km} + 35.87 \, \text{km} = 95.62 \, \text{km}$

Step 2: Calculate the Total Time

The total time includes both driving and the break:

• Driving Time: 88 minutes
• Break Time: 23 minutes

Total time: $\text{Total Time} = 111 \, \text{minutes} = \frac{111}{60} \, \text{hours} = 1.85 \, \text{hours}$

Step 3: Calculate the Average Speed

Now, we can calculate the average speed:
