Answer:
Step-by-step 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.
