an experiment that measures the distances that his toy car travels in two trials
an experiment that measures the distances that his toy car travels in many repeated trials
an experiment that measures the distances that his toy car travels in many repeated trials
an experiment that measures the distances that different toy cars travel in two trials
an experiment that measures the distances that different toy cars travel in two trials
an experiment that measures the distances that different toy cars travel in many repeated trials

answers
Both options 1 and 3 would be suitable experiments for testing the distance the toy car will travel down the ramp. However, option 3, which involves measuring the distances in many repeated trials, would provide a more accurate average distance. Therefore, the best response is:
an experiment that measures the distances that his toy car travels in many repeated trials
The best experiment to test how far Tony's toy car will travel when released down the ramp is: "an experiment that measures the distances that his toy car travels in many repeated trials."
Explanation:
To accurately determine the average distance the toy car will travel, it is important to conduct multiple trials. By measuring the distances in many repeated trials, Tony can account for any inconsistencies or variations in the car's performance. This will provide a more reliable average distance measurement. Conducting just two trials may not provide enough data for a statistically significant result. Therefore, multiple repeated trials will give a more comprehensive understanding of the toy car's average distance traveled.
