Final answer:
The incomplete statement about Mike's motorcycle speed could be true if his speed remains consistently at 20 m/s over a specified time. However, it could vary if considering velocity, which includes direction, or if his speed changes at all
Step-by-step explanation:
The question seems incomplete, but it appears to be discussing Mike's motorcycle speed. In physics, velocity and speed are measures of how quickly an object moves. Velocity also includes direction, whereas speed does not. Given the information provided, there's no way to definitively accept or reject the statement without additional context or a specified time frame for Mike's journey, or knowing if we're consistently talking about speed or velocity.
If we're only considering the magnitude of Mike's motion, i.e., his speed, and if it remains consistently at 20 m/s over a specific time period, then the statement would be true. But if we consider it in terms of velocity, which factors in direction, or if his speed changes at all during the specified time frame, the truth of the statement could vary.
