Answer:
The unit rate is [tex]24\ ft/min[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]
Let
x ------>the time in minutes
y -----> the distance in feet
This problem represent a proportional variation
so
The unit rate is the constant of proportionality (slope) of the direct variation
Observing the table
For x=5, y=120
[tex]k=y/x[/tex]
substitute
[tex]k=120/5[/tex]
[tex]k=24\ ft/min[/tex]
therefore
The unit rate is [tex]24\ ft/min[/tex]
