mercury : 5.8 • 107 = 620.6
Venus : 1.1 • 108 =118.8

so Venus is about 501.8 kilometers from then sun then mercury
B because 1/50 degrees Celcius is 0.02. The order would be -0.17,-0.10,0.02,0.10,0.54,which is B. Or you can order it in years: 1964,1958,1978,1965,2002.
It would be D because 0.0016*250,000= 400 and 250,000-400=249600
25% is the answer i hope this helps
