Select two pieces of information that are necessary to calculate an object's average speed. direction of the object's motion B. magnitude of the object's acceleration C. total time the object was in motion D. total mass of the object E density of the object F total distance the object traveled

## Step 1<br />The average speed of an object is calculated by dividing the total distance traveled by the total time taken. This is represented by the formula:<br />### **Average Speed = \(\frac{Total Distance}{Total Time}\)**<br />## Step 2<br />From the formula, it is clear that the total distance traveled (F) and the total time the object was in motion (C) are necessary to calculate the average speed.<br />## Step 3<br />The direction of the object's motion (A), the magnitude of the object's acceleration (B), the total mass of the object (D), and the density of the object (E) are not necessary to calculate the average speed.
