Explanation :
Speed of an object is defined as the total distance covered divided by total time taken by it.
Mathematically, it can be written as :
[tex]speed=\dfrac{total\ distance}{total\ time}[/tex]
Let d is the total distance covered and t is the time taken. Then the speed s is given by :
[tex]s=\dfrac{d}{t}[/tex]
Distance is taken in meters (m).
Time is taken in seconds (s).
So, the speed of an object is taken in m/s.
Hence, this is the required solution.
