Distance=speed*time
d=st t=d/s
%282.29%2A10%5E11%29%2F%283%2A10%5E8%29=7.63%2A10%5E2
How we got 10^2. when we divide 10^11 by 10^8 we subtract the powers to get 10^3.
2.29/3=.763...
we move the decimal point to the right 1 space giving 7.63...
we decrease the power of 10^3 to 10^2 to account for moving the decimal point.
