Answer:
total distance is 40 + 60 = 100 km
b The uniform motion is identical to the actual speed of the object. The non-uniform motion is different from the actual speed of the object. Uniform motion covers equal distance at an equal time interval. Non-uniform motion covers unequal distance at equal time interval.
