Final answer:
To find the time it would take John to run 2 kilometers, set up a proportion using his speed. Convert 3 miles to kilometers using a conversion factor. Round the answer to the nearest minute.
Step-by-step explanation:
To determine how long it would take John to run 2 kilometers, we can use the given information of his speed. John takes 25 minutes to run 3 miles. We can convert the distance to kilometers by multiplying by a conversion factor of 1.60934 kilometers per mile. So, 3 miles is approximately equal to 4.82803 kilometers. Now, we can set up a proportion to solve for the time it would take John to run 2 kilometers:
25 minutes / 4.82803 kilometers = x minutes / 2 kilometers
By cross multiplying, we can find the value of x, which represents the time it would take John to run 2 kilometers. Rounding the answer to the nearest minute, we can determine how long it would take John to run 2 kilometers.
