If a student rides her bicycle on a straight line and does not speed up or slow down, she is traveling with a? a) constant acceleration b) constant velocity c) positive acceleration d) negative acceleration

The correct answer should be B) Constant Velocity.
In physics, velocity is defined as the displacement divided by time where displacement is defined as the difference between your final and initial positions. Therefore, when an object travels the same distance every second, the object is said to be moving with constant velocity.
Hope this helps!!!:)

therefore, the efficiency is:
