Answer:
height / shadow = height / shadow until sun moves or earth tilts
12/9 = h / 6
h = 6*12 /9 = (3*2*3*4 ) / (3*3) = 2 * 4 = 8
So C. 8ft
6.5 hours is equal to:
60 mins x 6 + 30 mins = 390 mins
------------
42.25 / 390 = 13/120
------------
Now there are 60 minutes in an hour, so what we do is multiply 13/120 by 60 to find out how much you earn per hour...
13/120 x 60 = 6.5
--------------
You earn $6.50 per hour.
