Considering the definition of speed, you will travel 90 km.
What is speed
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]
Distance traveled
In this case, you know that:
- speed= 120[tex]\frac{km}{hr}[/tex]
- displacement= ?
- time= 0.75 hr
Replacing in the definition of speed:
[tex]120\frac{km}{hr} =\frac{displacement}{0.75 hr}[/tex]
Solving:
120[tex]\frac{km}{hr}[/tex]× 0.75 hr= displacement
90 km= displacement
In summary, you will travel 90 km.
