The problem with dividing by 3 is that the number of seconds you counted isn’t always evenly divisible by 3. If you counted 5 seconds, and you suck at math, how are you going to know that the answer is 1.67km? Sure you can always estimate and say “it’s one to two kilometers away”, but that doesn’t sound as smart as knowing the right answer. So here’s an easy way to multiply by 0.35 and get a fairly accurate distance:

a) Multiply the number of seconds by 3, this should be easy since it’s usually less than 10 seconds. If you have trouble with your three-times-tables, just add the number to itself twice, i.e. 8 + 8 =16, + 8 = 24

b) Now halve the number of seconds and add it to the total from step a. If it doesn’t divide evenly in two, just round it up (9 / 2 = 5).

c) Now just divide the total by 10, by simply moving the decimal place once to the left.

So if you counted 7 seconds, you would get 21 from step a, plus 4 from step b, which equals 25, and with step c your final answer becomes 2.5km.

Of course, if you have a calculator and stopwatch on your cell phone, you can get a much more accurate answer.
