Question

Mr. Cvetanovich decided that today was a great day for a jog. So he took off running west for 6 blocks,

North for 4 blocks, west for 7 blocks, south for 8 blocks, east for 13 blocks and finally North for 4 blocks. If


he were to look at his fitbit and see that his average speed was 7 miles per hour, what is the fitbit


calculating Velocity or Speed? Give evidence to support your argument. Also, what is the difference in


speed and velocity and give an example of when each is a more effective measurement.

Answer 1

Step-by-step explanation:

Fitbit calculates average speed, which is total distance traveled ÷ total time. He jogged a total of 6 + 4 + 7 + 8 + 13 + 4 = 42 blocks

Velocity is displacement ÷ time

His displacement (difference between point of origin and end point) was 2 blocks west. In other words, he ended up 2 blocks west of where he started.

Speed (scalar quantity) is an effective measurement for races (how fast a runner or a car went).

Velocity (a vector) is an effective measurement for tracking storms and airplanes (how fast is it going and in what direction).
