Final answer:
The equation for calculating average speed of an object is (d/t).
Step-by-step explanation:
The equation for calculating the average speed of an object is v = (d/t), where v is the average speed, d is the distance traveled, and t is the time taken for the travel.
For example, if an object travels a distance of 100 meters in 10 seconds, the average speed can be calculated as v = 100/10 = 10 m/s.
Therefore, the correct option is a) v = (d/t).
