Using proportions, it is found that 400 light years have 3.6 \times 10^{18} meters.

  • To find how many meters are 400 light years, we use proportions, with a rule of three.
  • One light year has 9 \times 10^{15} meters.
  • How many meters are there in 400 light years, which in scientific notation, is 4 \times 10^2 light years?

The<u> rule of three</u> is:

1 light year - 9 \times 10^{15} meters.

4 \times 10^2 light years - x meters

Applying cross multiplication:

x = 9 \times 10^{15} \times 4 \times 10^2 = 36 \times 10^{17} = 3.6 \times 10^{18}

Thus, 400 light years have 3.6 \times 10^{18} meters.
