If you can swim 20 laps around the track in 2 hours what is the average speed
If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes his average speed (pace) is 1.0285 meters per second.
You will have to maintain an average speed of 4.5 mph
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Yes.
Goldie swims a total of 20*0.5 miles = 10 miles.She does so in 2 hours.Her average speed is therefore 10 miles per 2 hours.You can further simplify this by dividing both measures by 2.10 miles per 2 hours5 miles per 1 hour.She swam very fast: 5 mph.

Average speed may be calculated by dividing the length of the track by the time it takes to complete one circuit.
Her average speed is greater than her average velocity.
Yes, if you run around a track at a constant speed of 5 km/h, your velocity is constant because velocity includes both speed and direction. As long as you maintain this speed and direction, your velocity remains constant.

The California Speedway is now known as Auto Club Speedway. The average track speed reaches over 200 miles per hour while the fastest lap is 241.428 miles per hour.
Even though the person is moving at a constant speed, they are changing direction constantly as they go around the track. Since acceleration is defined as any change in velocity, and velocity includes both speed and direction, the person running on a circular track is experiencing acceleration.
