look at the units!!! ok, forget the speed of light, seeing how its pretty much instantaneous unless you're 1 million miles away from the source...so, look at the units of the 14.2 s and 343 m/s...so......how do you get the distance to be by itself! multiply: (14.2 s)(343 m/s) the seconds will cancel each other out and you'll be left with meters! it ends up being 4,870.6 meters. remember, in physics when you're trying to solve a word problem, at first forget the numbers and look at the units. solve for the units first, then plug in the numbers.
