Final answer:
The average speed of the car traveling from the 100-meter mark to the 250-meter mark in 10 seconds is 15 meters per second (m/s).
Step-by-step explanation:
The student is asking about calculating the average speed of a car as it travels between two points on a highway. To find the average speed, you use the formula:
Average Speed = Total Distance / Total Time.
In this case, the car travels from the 100-meter mark to the 250-meter mark, which is a total distance of 150 meters (250 meters - 100 meters). This travel is completed in a time of 10 seconds. Using the formula, the average speed of the car would be:
Average Speed = 150 meters / 10 seconds = 15 meters per second (m/s).
This is a straightforward application of the concept of average speed in Physics, which is relevant for students to understand motion and its measurement.
