B.) 3.250*106 days
I figured it out!! Yay!
You take 7.8 and divide it by 24 which will get you 0.325
In order to get it match one of the options, multiply it by 10 (which will add 1 to 105!) Leaving you 3.25*106
Use formula A²+B²=C²
120²+62²=C²
14,400+3,844=C²
14,400+3,844=18,244
√18,244=135.07035...
135.07035...≈135.1
