Ok, first we need to organize. <span>14, 8, 23, 9, 11, 27, 22, 3, 17, 12, 29 </span>3, 8, 9, 11, 12, 14, 17, 22, 23, 27, 29.
First, we need to find the median, the or the middle, which is 14. Now that we know the median is fourteen, we take away all numbers to the left of 14, including 14: 17, 22, 23, 27, 29. Now just find the median in this new set of numbers. This will give us our upper quartile, which is 23. Hope this helped, and don't forget to drop a like.
If you're going 804 miles in 16 hours, you're going to want to do 804 / 16, which is 50.25, so you're going either 50.25 mph or 50 1/4 mph depending on the format you choose.
Your problem is missing the units after the numbers. It could be 4 cents and 32 cents, 4 dollars and 32 dollars, 4 cents and 32 dollars, 4 dollars and 32 cents, etc.
