Answer:
Average velocity is 28 units along the line.
Step-by-step explanation:
Here given that s(1) = 114 and s(6) = 254
We need to find average velocity between [1,6],
Average velocity is the ratio of displacement and time,
Displacement = s(6)-s(1) = 254 - 114 = 140 units
Time = 6 - 1 = 5 units

Average velocity is 28 units along the line.
