Hadi, is there any other way ?Maximum speed = Upper limit of distance/Lower limit of time = 40.1/2.55 ≈ 16.4
Minimum speed = Lower limit of distance/Upper limit of time = 39.9/2.45 ≈ 15.6
Range of uncertainty = (Maximum - Minimum)/2 = (16.4 - 15.6)/2 = ± 0.4 m/s
Answer : C
I do something completely different than you did.
So I mean, do you solve uncertainty questions like this only ?
