if u have swam one lap in a swimming pool, that means from one end to the other and back. In 3.5 h, a swimmer makes exactly 60 laps in the pool, that is 40 m long. Determine the distance the swimmer traveled, the total displacement of the swimmer, the swimmer's average velocity and the swimmer's average speed

60*80m/3.5 hr = 1371 m/hr

knowing that speed you can do the rest. But watch out when doing velocity, which is not the same as speed.

To determine the distance the swimmer traveled, you can multiply the number of laps by the length of each lap. In this case, the swimmer completed 60 laps, and the length of each lap is 40 meters.

Distance = Number of laps * Length of each lap
Distance = 60 laps * 40 meters/lap
Distance = 2400 meters

Therefore, the swimmer traveled a total distance of 2400 meters.

Next, let's determine the total displacement of the swimmer. Displacement refers to the straight-line distance from the initial position to the final position. In this case, since the swimmer started and ended at the same point, the displacement is zero. The swimmer's total displacement is 0 meters.

Now, let's calculate the swimmer's average velocity. Velocity is a vector quantity and is given by the displacement divided by the time taken.

Average velocity = Displacement / Time

Since we determined that the displacement is zero, the average velocity would be zero as well.

Finally, let's calculate the swimmer's average speed. Speed is a scalar quantity and is given by the total distance traveled divided by the time taken.

Average speed = Total distance / Time

We already know the total distance traveled (2400 meters) and the time taken (3.5 hours but expressed in the same unit as distance, so we'll need to convert it). There are 3600 seconds in an hour, so:

Time (in seconds) = Time (in hours) * 3600 seconds/hour
Time (in seconds) = 3.5 hours * 3600 seconds/hour
Time (in seconds) = 12600 seconds

Now, we can calculate the average speed:

Average speed = 2400 meters / 12600 seconds
Average speed ≈ 0.1905 m/s

Therefore, the swimmer's average speed is approximately 0.1905 meters per second.
