To convert the speed of Stephen Kiprotich from miles per minute to kilometers per minute, you can follow these steps:
-
Convert miles to kilometers:
- We know that 1 mile is approximately equal to 1.60934 kilometers. Therefore, we can convert the distance of the marathon into kilometers.
-
Convert the marathon distance:
- The marathon distance is 26.219 miles. To find the equivalent in kilometers: \[ \text{Distance in kilometers} = 26.219 \text{ miles} \times 1.60934 \text{ km/mile} \]
-
Complete the multiplication:
- Calculate \( 26.219 \times 1.60934 \).
-
Determine the time in minutes:
- The time taken to complete the marathon is given as 128 minutes.
-
Calculate speed in kilometers per minute:
- Speed is calculated by dividing the distance by the time: \[ \text{Speed} = \frac{\text{Distance in km}}{\text{Time in minutes}} \]
-
Final calculation:
- Use the values obtained from steps 2 and 4 to find the speed.
By following these steps, you will be able to find Stephen Kiprotich's speed in kilometers per minute. Let's carry out the calculations:
-
Convert 26.219 miles to kilometers: \[ 26.219 \text{ miles} \times 1.60934 \text{ km/mile} \approx 42.195 \text{ km} \]
-
Time is 128 minutes.
-
Calculate speed: \[ \text{Speed} = \frac{42.195 \text{ km}}{128 \text{ minutes}} \approx 0.329 \text{ km/min} \]
Therefore, Stephen Kiprotich's speed in kilometers per minute is approximately 0.329 km/min.
