ANSWER:
A. Repeated experiments with airplanes and how their velocity changes as a result of environmental conditions like wind can help scientists develop a model for flight paths and launch times to minimize fuel usage
Explanation:
The experiments with speed and speed are important mainly for the calculation of time and thus be able to take advantage of it in a better way, be it time or some valuable resource related to it.
With this in mind, the only option that fits is option A. Repeated experiments with airplanes and how their velocity changes as a result of environmental conditions like wind can help scientists develop a model for flight paths and launch times to minimize fuel usage
