Amaya ran around 3 times around a 1 mile track in 45 minutes, what was her average velocity for the trip?

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:

-----------

In this question the variables are classified as:

Displacement = 3 miles

Change in Time = 45 minutes

-----------

Now, fill in the expression to solve.

-----------

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

where's the following? you gotta add it to know what the choices are
