Question

Your friend just challenged you to a race. You know in order to beat him, you must run 15 meters within 20 seconds in a northern direction. What does your average velocity need to be to win the race? (2 points)
.5 meters per second, north
.75 meters per second, north
1.3 meters per second, north
300 meters per second, north

Answer 1

velocity = distance / time

what is our distance?
what is the time you're running that distance in?

Answer 2

15 meters in 20 seconds

Answer 3

so 15 meters is our distance
and time is 20 seconds

velocity = distance / time

velocity = 15 meters / 20 seconds

what is 15/20 = ?

Answer 4

so it would be .75

Answer 5

yes! And remember that velocity is a vector

that means it also has a direction to it
(and obviously all the answer choices say north so you know what the correct direction is)
