Stephen Kiprotich, the 2012 Olympic marathon winner, completed the 26.219 miles in 128 minutes. What was his speed in kilometers per minute?

What steps should you take to solve this problem?

Answer 1

Here is the sample response:

Explanation:

Find the speed by dividing 26.219 by 128. Convert miles to kilometers by multiplying by the conversion factor, with miles in the denominator and kilometers in the numerator.

Answer 2

First, we must convert the total miles into kilometers. If there are 1.609 kilometers in one mile, then 26.219 miles equals 42.3 kilometers. We then divide by the total minutes (128) to get the speed in kilometers per minute which should be 0.32 or 0.3 kilometers per minute.
