If you are driving $95~\mathrm{km/h}$ along a straight road and you look to the side for $2.0~\mathrm{s}$, how far do you travel during this inattentive period?

Solution:

A motion which covers equal distance in equal interval of time is called a Uniform motion.

To compute speed of motion, we simply divide the distance of travel by the time of travel.

$$v = \frac{d}{t}$$

Thus, the distance is

$$d = v t$$

In our case

$$v = 95~\mathrm{km/h} = 95 \cdot \frac{1000}{3600} = 26.39~\mathrm{m/s},$$ $$t = 2.0~\mathrm{s}$$

Thus,

$$d = 26.39 \cdot 2.0 = 52.78~\mathrm{m}$$

Answer: $d \approx 52.8~\mathrm{m}$
