If a speedometer currently reads 62 mph, but only 54 miles have been covered during the last hour, what is the average speed? Is it 62 mph, 54 mph, or the average of those two. I can come up with reasonable ways for any of them to be the answer, but right now I'm leaning towards 54 mph, because if they have been traveling for an hour and you have gone 54 miles, that would be 54 mph right? I just don't get how the 62 mph fits in.
