Using the graph, we can see that the runner ran 0 m at the beginning of the race. For example, we might say that a car has an average speed of 25 miles per hour. Average speed is the total distance traveled for the object in question divided by the total elapsed time taken to travel the distance, the total period of time. Average Speed = Total Distance/Total Time When the initial velocity is 0 then the displacement=final velocity. It's a scalar quantity which means it is defined only by magnitude. 2. 3. At the end of your trip, your friend tells you that your average speed during the trip is 36 miles per hour. Calculating Average Speed. If the speed of the particle is high it means the particle is moving fast and if it is low, it means the particle is moving slow. What was his average speed in miles perhour? Speed is ascalar quantity. The Humboldt squid can travel 399.6 meters in 60 seconds, so s=399.6m60seconds=6.67m/ss=\frac{399.6m}{60seconds}=6.67m/ss=60seconds399.6m=6.67m/s, significantly faster than the fastest human swimmer. Plug those two given numbers into the triangle in their two corners to get: If you know two of the three variables, distance, time, and speed, then you can use algebra to find what you're missing.
