kiley went 5.7 km/h north and then went 5.8 km/h west. from start to finish, she went 8.1 km/h northwest. which best describes her numbers? 5.7 km/h north and 5.8 km/h west are instantaneous speeds, while 8.1 km/h northwest is the average speed. 5.7 km/h north and 5.8 km/h west are average speeds, while 8.1 km/h northwest is the instantaneous speed. 5.7 km/h north and 5.8 km/h west are average velocities, while 8.1 km/h northwest is the instantaneous velocity. 5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.

Answer

Brief Explanations:

Instantaneous velocity is the velocity of an object at a particular moment in time, and average velocity is the total displacement divided by the total time. Here, the velocities in specific directions (north and west) and the overall velocity from start - to - finish are being compared. The velocities in the north and west directions are likely instantaneous as they describe motion at specific parts of the journey, and the velocity from start - to - finish is an average over the whole journey considering the overall displacement.

Answer:

5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.
