An experimental study involves the researcher seeking to affect the results on purpose. The given situation is an observational study.
<h3>What are surveys, experiments, and observational studies?</h3>
- Surveys are one type of observational study since the researchers have no control over the results. Statistical surveys collect data from a sample group in order to learn more about the overall population.
- The sample population being examined is measured, or surveyed, in observational research. The researcher watches the individuals and measures variables but makes no attempt to influence the population or intervene in the study.
- In contrast to an observational study, an experimental study involves the researcher seeking to affect the results on purpose. The objective is to find out what influence a certain therapy has on the result.

Answer:
55 miles per hour
Step-by-step explanation:
Given that:
Distance from Mexico to Texas 350 miles
Miles already traveled = 75 miles
Hence, miles left ;
(350 miles - 75 miles) = 275 miles
To complete 275 miles in 5 hours ;
Speed = distance / time
Speed = 275 / 5
Speed = 55 miles per hour
