Question

Wilson kipsang set new world record time of approximately 2 hours and 3 minutes. What was his average speed in mile per hour

Answer 1

26.219 miles is the distance for a marathon.

 

2 hrs 3 min = 2 3/60 hrs = 2 1/20 hours = 2.05 hours

 

(26.219 miles)/(2.05 hours) = 12.79 miles per hour
