A person jogs eight complete laps around a quarter-mile track in a total time of 13.1 minutes

A) Calculate the average speed, in m/s

B) Calculate the average velocity, in m/s

Speed and velocity have the same magnitudes. The only difference is that speed is a scalar quantity and velocity is a vector quantity. In other words, speed is just a magnitude, while velocity is a magnitude with direction. They're essentially the same.

Let's convert miles to meters and minutes to seconds

1/4 mile = 402.34 meters (1 mile = 1609 m)

13.1 minutes = 786 seconds (1 minute = 60 seconds)

Speed is calculated as distance over time, thus,

Speed = (402.34 meters) * 8/786 seconds

a.) Speed = 4.1 m./s

b.) Velocity = 4.1 m/s
