Since Amaya ran around a 1 mile track 3 times we can multiply this to find the total distance she traveled (displacement).
3 x 1 = 3 miles traveled.
-----------
Formula: [tex]V_a_v_g~=~\frac{displacement}{change~in~time}[/tex]
-----------
In this question the variables are classified as:
Displacement = 3 miles
Change in Time = 45 minutes
-----------
Now, fill in the expression to solve.
[tex]V_a_v_g~=~\frac{45}{3}\\V_a_v_g~=~15~[/tex]
-----------
Amayas average velocity is 15 minutes per mile.

Average Velocity = (displacement) / (time)
Displacement = distance and direction between the start-point and end-point, no matter what happens in between.
Amaya ran around the track, so she ended in the same place she started. The distance between her start-point and end-point was zero. So . . .
Average Velocity = zero.
= = = = = = = = = =
Average Speed = (distance covered) / (time to cover the distance)
Amaya's distance = (1 mile/track) x (3 tracks) = 3 miles
Time to cover the distance = (3/4 hour)
Average speed = (3 miles) / (3/4 hour)
Average speed = (3 ÷ 3/4) mi/hr
Average speed = (3 x 4/3) mi/hr
Average speed = 4 miles per hour
