Waste some time
Have a donut and some coffee
While you are supposed to be working


You have decided to take your morning run in preparation for the local marathon at an average speed of 6 miles per hour. Unfortunately you are not in as good a shape as you thought and you are running uphill. You find that complete half of the run, all uphill, at an average of only 3 miles per hour. How fast must your run to make the trip, all downhill, at an average speed for the entire round trip of 6 miles per hour?
