Answer:
Option C. 30 m
Explanation:
From the graph given in the question above,
At t = 1 s,
The displacement of the car is 10 m
At t = 4 s
The displacement of the car is 40 m
Thus, we can simply calculate the displacement of the car between t = 1 and t = 4 by calculating the difference in the displacement at the various time. This is illustrated below:
Displacement at t = 1 s (d1) = 10 m
Displacement at t= 4 s (d2) = 40
Displacement between t = 1 and t = 4 (ΔD) =?
ΔD = d2 – d1
ΔD = 40 – 10
ΔD = 30 m.
Therefore, the displacement of the car between t = 1 and t = 4 is 30 m.

A or E I think cous I use to do this in yr 7
There's no general rule.
Displacement is the length of a straight line from start to finish, and distance is how far you actually traveled from start to finish.
The only thing we really know is that distance can never be shorter than displacement. So I guess the answer is:
<em>The numerical ratio of displacement to distance is always 1 or less</em>.
