      Hello FunnyAntimony5289!

      Thank you for your question! :)

      First, you need to look at a chart of the International System of Units! Here’s one:

      Next, ask yourself this question: In scientific notation, how could I rewrite my measurement?

      For 205,000,000 m = 205 × 10⁶ m! And this value corresponds to mega!

      So, we can write it as 205 Mm! :)

      We do the same thing for the other measurements!

      For 0.0542 s, we can rewrite it as 5.42 × 10⁻³!

      So, it corresponds to milli!

      The answer will therefore be 5.42 ms! :)

      I hope I answered your question! Don’t hesitate to come back and see us if you have any other questions! :D

      Have a great evening! :)
