  1. 20 km / 26 minutes = average speed of 10/13 km per minute. 1 kilometer is approximately 0.621 miles, so 10 kilometers is 6.21 miles. So then, the average speed is 6.21/13 miles per minute. There are 60 minutes per hour, so then the average speed in miles per hour is 60 * 6.21 / 13 = about 28.66 miles per hour. Thus, the answer is (A).
