Final answer:
The sailboat travels 20 meters in 8.0 seconds, given its constant velocity of 2.5 m/s, as calculated by multiplying distance and time.
Step-by-step explanation:
The student asked how far a sailboat moving at a constant velocity of 2.5 m/s would travel in 8.0 seconds. To find the distance traveled, we use the formula distance = velocity × time. Here, the velocity is 2.5 m/s, and the time is 8.0 seconds. Multiplying these two values together:
distance = 2.5 m/s × 8.0 s = 20 meters.
Therefore, the sailboat travels 20 meters every 8.0 seconds, which corresponds to option (a).
