Question

The plane flight covers 400 miles in the first hour. As you approach the landing site, it takes you an hour to cover the last 200 miles. This is an example of (2 points) positive acceleration. velocity. instantaneous speed. negative acceleration.

Answer 1

Miles per hour is velocity so I agree with you. Without seeing any associated question, though, it's hard to say. If the question is, find the average velocity, then velocity is correct. But since change in velocity is negative, that is also negative acceleration.

Answer 2

negative acceleration

Step-by-step explanation:

Acceleration is defined as the rate of change in velocity to the time taken.

Acceleration is positive if the final velocity is ore than the initial velocity.

Acceleration is negative if the final velocity is less than the initial velocity.

Here, the velocity of plane is decreasing because it is landing, so the acceleration is negative.
