The runner's average speed was 6.5 km/h, and he finished running at 16:08.
Solución
Let's solve the problem step by step.
### Step 1: Extract Known Conditions
- Start time: \( 14:08 \)
- Duration of running: \( 2 \) hours
- Distance covered: \( 13 \) kilometers
### Step 2: Calculate Average Speed
We will use the formula for speed:
\[
\text{Speed} = \frac{\text{Distance (km)}}{\text{Time (hours)}}
\]
Substituting the known values:
- Distance = \( 13 \) km
- Time = \( 2 \) hours
Now, we can calculate the average speed:
\[
\text{Speed} = \frac{13}{2}
\]
Let's perform the calculation.
### Step 3: Perform Calculation for Speed
Now, I will calculate the average speed.
\[
\text{Speed} = \frac{13}{2} = 6.5 \text{ km/h}
\]
### Step 4: Calculate Finish Time
To find the finish time, we add the duration of running to the start time.
- Start time: \( 14:08 \)
- Duration: \( 2 \) hours
Adding \( 2 \) hours to \( 14:08 \):
\[
14:08 + 2:00 = 16:08
\]
### Final Answers
4.1 The average speed of the runner during his run is \( 6.5 \) km/h.
4.12 The runner finished his run at \( 16:08 \).

Bonus Knowledge
To calculate the average speed of the runner, we can use the formula for speed: Speed \( = \frac{\text{Distance in km}}{\text{Time in hours}} \). The runner covered 13 kilometers in 2 hours. Using the formula, we have: \[ \text{Speed} = \frac{13 \text{ km}}{2 \text{ hours}} = 6.5 \text{ km/h} \] So, the average speed of the runner is 6.5 km/h. For the finishing time, the runner starts at 14:08 and runs for 2 hours. Adding 2 hours to 14:08 results in: \[ 14:08 + 2:00 = 16:08 \] Thus, the runner finished his run at 16:08.
