Question

Marisa has a remote control toy car. All of her classmates help her measure the car's distance from the starting line every second. The graph shows all the measurements that the class made.

Which of Marisa's classmates describes the toy car's motion correctly?

Answer 1

The classmate who describes the toy car's motion correctly is the one whose measurements show a constant increase in distance every second.

The classmate who describes the toy car's motion correctly is the one whose measurements show a constant increase in distance every second.

Looking at the graph, we can see that the distance of the car from the starting line increases by the same amount each second. This indicates a constant speed.

For example, if the classmate measured the distance to be 1 meter at the first second, then 2 meters at the second second, and 3 meters at the third second, the car is moving at a constant speed of 1 meter per second.

In summary, the classmate whose measurements show a constant increase in distance every second accurately describes the toy car's motion.
