Considering the definition of velocity, the speed of Sarah is 0.05 [tex]\frac{miles}{minutes}[/tex].
Definition of velocity
Speed is a quantity that expresses the relationship between the space traveled by an object. That is, the speed is associated with the change of position of an object in space within a certain amount of time.
The speed can be calculated using the expression:
[tex]speed=\frac{displacement}{time}[/tex]
Speed has units of [tex]\frac{distance}{time}[/tex].
Speed of Sarah
In this case, you know:
- displacement= 1.5 miles
- time= 30 minutes
Replacing in the definiiton of speed:
[tex]speed=\frac{1.5 miles}{30 minutes}[/tex]
Solving:
Speed= 0.05 [tex]\frac{miles}{minutes}[/tex]
Finally, the speed of Sarah is 0.05 [tex]\frac{miles}{minutes}[/tex].
