The speed of the car is 60 m/s
Explanation:
The speed of an object is a scalar quantity telling "how fast" the object is moving, regardless of its direction. It can be calculated as follows:
[tex]speed=\frac{d}{t}[/tex]
where
d is the distance covered
t is the time taken
For the car in this problem, we have
[tex]d=108 km =1.08\cdot 10^5 m[/tex] is the distance covered
[tex]t=30 min \cdot 60 =1800 s[/tex] is the time taken
Subsituting into the equation, we find the speed:
[tex]speed=\frac{1.08\cdot 10^5}{1800}=60 m/s[/tex]
