C average speed is used, which is total distance divided by total time.
Explanation:
From the analogy presented, we know that because the speed at which an object travels varies over time, the average speed is used.
The average speed is is the total distance traveled divided by the total time taken.
The average speed appropriately reflects changes in rate of speed with time.
It accounts for moments where a car slows and speeds up.

To add fractions with different denominators you must convert the denominators into the lowest common factor. Aka the multiple they all go into. You then times the numerator by what you timsed the denominator by to make sure they both have the same denominator.
Example:
2/5+4/10
They both go into 10.
4/10+4/10= 8/10. 2 became 4 because 5x2=10.
I hope this helped!
You could also simplify 8/10 into 4/5z
