t1 = 1 h.
S1 = 50 km.
t2 = 3 h.
S2 = 200 km.
V1 -?
V2 -?
Uniform movement is called such a movement in which the body, in any equal intervals of time, travels equal distances. With uniform motion, the body’s velocity V does not change.
Not uniform is a movement in which the body travels different distances at equal intervals of time.
The speed of movement of the body V is the ratio of the traversed path S to the time of its passage t: V = S / t.
V1 = S1 / t1.
V1 = 50 km / 1 h = 50 km / h.
V2 = S2 / t21.
V2 = 200 km / 3 h = 66.7 km / h.
Since V2> V1 this is not a uniform movement.
Answer: the car was moving unevenly.
