Need ! 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?

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.
