A motorcyclist, a car and an rv depart on the same day and time from Barcelona towards Stockholm. The average speed of the motorcycle is 125 km per hour and on average it travels for 6 hours daily. The car on average drives at 120 km per hour and it travels an average of 6.5 hours. The rv on average goes at 110 km per hour for about 7.5 hours each day. Which of the 2 vehicles will get first to Stockholm? How long will each take (please tell in days, hours, and minutes) to take this trip?

To determine which vehicle will arrive first in Stockholm, we need to calculate the time it takes for each vehicle to travel the distance from Barcelona to Stockholm. We'll assume that all three vehicles take the same route. 

### Step 1: Calculate the distance between Barcelona and Stockholm
Let's assume the distance between Barcelona and Stockholm is approximately 2,500 km (this is a rounded estimate for simplicity).

### Step 2: Determine the daily distance each vehicle covers

1. **Motorcycle:**
   - Average speed: 125 km/h
   - Daily travel time: 6 hours
   - Daily distance: \( 125 \, \text{km/h} \times 6 \, \text{hours} = 750 \, \text{km/day} \)

2. **Car:**
   - Average speed: 120 km/h
   - Daily travel time: 6.5 hours
   - Daily distance: \( 120 \, \text{km/h} \times 6.5 \, \text{hours} = 780 \, \text{km/day} \)

3. **RV:**
   - Average speed: 110 km/h
   - Daily travel time: 7.5 hours
   - Daily distance: \( 110 \, \text{km/h} \times 7.5 \, \text{hours} = 825 \, \text{km/day} \)

### Step 3: Calculate the number of days each vehicle will take to cover 2,500 km

1. **Motorcycle:**
   - Number of days: \( \frac{2500 \, \text{km}}{750 \, \text{km/day}} = \frac{2500}{750} \approx 3.33 \, \text{days} \)
   - Convert 0.33 days to hours and minutes:
     - 0.33 days = \( 0.33 \times 24 \, \text{hours/day} \approx 7.92 \, \text{hours} \)
     - 0.92 hours = \( 0.92 \times 60 \, \text{minutes/hour} \approx 55 \, \text{minutes} \)
   - **Time taken:** 3 days, 7 hours, 55 minutes

2. **Car:**
   - Number of days: \( \frac{2500 \, \text{km}}{780 \, \text{km/day}} \approx 3.21 \, \text{days} \)
   - Convert 0.21 days to hours and minutes:
     - 0.21 days = \( 0.21 \times 24 \, \text{hours/day} \approx 5.04 \, \text{hours} \)
     - 0.04 hours = \( 0.04 \times 60 \, \text{minutes/hour} \approx 2.4 \, \text{minutes} \)
   - **Time taken:** 3 days, 5 hours, 2 minutes

3. **RV:**
   - Number of days: \( \frac{2500 \, \text{km}}{825 \, \text{km/day}} \approx 3.03 \, \text{days} \)
   - Convert 0.03 days to hours and minutes:
     - 0.03 days = \( 0.03 \times 24 \, \text{hours/day} \approx 0.72 \, \text{hours} \)
     - 0.72 hours = \( 0.72 \times 60 \, \text{minutes/hour} \approx 43 \, \text{minutes} \)
   - **Time taken:** 3 days, 0 hours, 43 minutes

### Conclusion:
- **The RV will arrive first**, taking approximately 3 days and 43 minutes.
- **The car will arrive second**, taking approximately 3 days, 5 hours, and 2 minutes.
- **The motorcycle will arrive last**, taking approximately 3 days, 7 hours, and 55 minutes.

### Additional questions:

1. What is the total distance in kilometers between Barcelona and Stockholm?
2. How would changes in average speed impact the travel time of each vehicle?
3. What is the total number of hours each vehicle travels to reach Stockholm?
4. If the RV had to make an additional 2-hour stop every day, how would that affect its arrival time?
5. How does the daily travel time affect the overall duration of the trip?
6. What factors other than speed could influence the time it takes for these vehicles to reach Stockholm?
7. What would happen if each vehicle's speed was reduced by 10%? How would that affect the travel time?
8. How could traffic conditions impact the travel time of each vehicle?

### Tip:
Always consider the impact of varying travel conditions (like traffic, weather, or road work) when estimating travel times, as they can significantly alter your expected arrival time.
