Initial data: V (vehicle speed) = 40 km / h; S (distance traveled by the car) = 4 km.

SI system: V = 40 km / h = 40 * 1000/3600 m / s = 11.11 m / s; S = 4 km = 4 * 1000 m = 4000 m.

We calculate the time that the car will need using the formula: t = S / V.

Let’s perform the calculation:

t = 4000 / 11.11 = 360 s = 6 min.

Answer: Auto will take 360 seconds or 6 minutes.
