V = 108 km / h = 30 m / s.
S = 200 m.
t -?
The speed V = 108 km / h means that the body travels 108 km in 1 hour. We convert km to meters, hours to seconds: V = 108 km / h = 108 * 1000 m / 1 * 3600 s = 30 m / s.
Let us write down the formula for determining the speed of a body V with uniform rectilinear motion: V = S / t.
From the formula we express the time of movement: t = S / V.
t = 200 m / 30 m / s = 6.6 s.
Answer: the car will cover the distance S = 200 m in t = 6.6 s.
