Answer:
To figure out the object's speed between points A and B, we need
Option D: the time it took the object to move between points A and B
Explanation:
The formula for Speed is Change in position or distance traveled divided by time.
SI unit of speed is the metre per second.
An object moved from position A to B, that means it is the distance traveled. To calculate the speed, we need time taken for that object to move from position A to B. Thus, Option D: time taken to move from A to B, is the correct statement to be chosen from. We do not need the acceleration or direction or how fast the object was travelling as given in other options.
