I was always told that the accuracy of your measurement when using an analogue scale was half a division of your scale. In this case that would be 1 ms (half of a division, a division being 2 ms as stated).
Speed = dist/time, Dist = Speed*Time = 340 ms(^-1)*0.001s = 0.34m. You could argue that as the measurement you're looking for is half the overall distance, the error is 0.17m. Not sure where the 0.14 has come from.
