Which of the following units could be used for the average speed of an object

Explanation:

Speed measurements contain a unit of distance divided by a unit of time. Examples of units of speed might include “meters per second” (m/s), “kilometers per hour” (km/h), or “miles per hour” (mph or mi/hr).

Average speed can be calculated using the formula v=d/t where the variables are:

v is the average speed of the object with units of m/s

d is the total distance or length of the path of the object with units of m

t is the total time taken to cover the path with units of s

Speed cannot have a negative value.

Meters per second

I put that and it got right
