Final answer:
Without specific velocity or time data, we cannot calculate the average times the car took to travel the required distances. However, a rabbit running at 10 km/h has a speed of 2.78 m/s when converted.
Step-by-step explanation:
The question you've asked pertains to calculating average time, speed, and converting units within the context of a Physics class. Unfortunately, without specific data on the velocities or times taken by the car to travel the designated distances (0.25 meters and 0.50 meters), it is impossible to provide the average times requested.
According to the given context, the time it takes a car to travel certain distances can be determined if the speed is known or can be read from a graph, but not without this information.
For the rabbit running at 10 km/h, we can convert its speed to m/s:
speed in m/s = (speed in km/h) x (1000 m/km) / (3600 s/h)
speed in m/s = (10 km/h) x (1000 m/km) / (3600 s/h) = 2.78 m/s.
Regarding the car's position, without a graph or a given velocity, we cannot determine how many meters a car travels compared to walking a width of a car or how long it takes to travel 100 meters.
