How is average speed sometimes different than average velocity?
Average speed is the distance traveled divided by the time traveled. Average velocity is the displacement divided by the time traveled. Displacement is change in position, or final position (df) minus initial position (di). Let's say you traveled from your home to the mall and then back again. The total distance traveled was 30 miles, and the total time driven was 1 hour. Average speed = distance traveled/time traveled = 30 miles/1 hour = 30mi/hr or 30mph. Average velocity = (df - di)/time traveled = 0 mile/1 hour = 0 mi/hr or 0mph.* *In this case the final position and the initial position are the same (your house), so the displacement is zero. Something to think about: When a Nascar driver races 500 miles around an oval track, his average speed might be 160mph, but his average velocity when he finishes the race is 0mph.

Average speed and instantaneous speed?
Average speed = (distance covered) divided by (time to cover the distance). If I leave the house at 8:00 in the morning, drive 20 miles to the office, stay in my office until late afternoon, leave the office and drive 20 miles home, and arrive home at 6:00 in the evening, my average driving speed for the day is (40 miles) divided by (10 hours) = 4 miles per hour.
A cyclist leaves home and rides due east for a distance of 45 km she returns home on the same bike path if the entire trip takes 4h what is her average speed?
To find the average speed of the cyclist, we first determine the total distance traveled. The cyclist rides 45 km east and then returns 45 km home, making the total distance 90 km. The total time for the trip is 4 hours. Thus, the average speed is calculated as total distance divided by total time: 90 km / 4 h = 22.5 km/h.
