The answer rounded would be .83. I got this by writing out the equation each hour. For example, 1/2+1/2+1/2+1/2+6+1/2+1/2+1/2+1/2+0+0+0 = 10. Then, to find the average you divide them out by the amount of numbers. This would give you 10 divided by 12.
.63-(-9.85)= 10.48 I hope this helped. :)

500 inches is greater than 40 feet because, every 12 inches is 1 foot. Since every 12 inches is 1 foot you have to divide. 500÷12=41.6667. Hope this helps!
