So I have been working on this question ALL week long and have also posted it here. A few have helped me, but have never finished helping me and I'm clueless to say the least.
It asks how long light will take to reach earth. This formula is Rate Time = Distance.
So 5870 = 311,110 (5870 being the miles equaling light years and 311,110 equaling the distance.
So what do I do? Can someone walk me through this step by step please? I'd absolutely appreciate it!!

You are trying to solve for t (time).  Step 1:  arrange your formula with t by itself and on the left hand side of the = sign.

Let me see the new arrangement of the equation which solves for t.

Step 2.  Your information provided with the problem is:  The rate is in a weird unit "billion miles per year" or Bmpy.  The distance is in billion of miles.  Your answer will be in years.

Now just do the algebra:
t=d/r
t=311,110 billion miles/5870 billion miles per year|dw:1453845747830:dw|
