Final answer:

To find the moving time for a car to travel 100 meters, one must know the velocity and apply the formula d = do + vt. For the rabbit running at 10 km/h, its speed in m/s is 2.78 m/s. Without velocity or acceleration of the car, a calculated answer for time cannot be provided.

Step-by-step explanation:

Understanding Motion and Displacement

To determine how long it will take for a car to cover a distance of 100 meters, we need to understand the relationship between displacement, velocity, and time, represented by the formula d = do + vt. Here, d stands for the final displacement, do is the initial displacement, v is the velocity, and t is the time. To find the moving time when the distance d is given as 100 m and assuming the object starts from rest with constant acceleration, we could use the formula to rearrange for t.

If a rabbit runs at a speed of 10 km/h, to convert this speed to meters per second (m/s), we use the conversion factor: 1 km/h = 1000 m / 3600 s, which gives:
Speed in m/s = (10 * 1000 m) / (3600 s) = 2.78 m/s.

However, without knowing the velocity or acceleration of the car mentioned for the 100m travel time, we cannot give a complete calculated answer. We can only say that if we know the velocity of the car, we can use the formula above to solve for time.
