Answer: Use the formula [tex]Average\ speed=\frac{Total\ distance}{Elapsed\ time}[/tex] (SEE EXPLANATION)
Step-by-step explanation:
Since the exercise it is incomplete, I will give you a general explanation about how to solve this problem so you can find the solution.
For this exercise it is important to remember that , by definition the average speed is a scalar quantity that can be calculated dividing the Total distance divided by the Elapsed.
It is also important to know that the Elapsed time is defined as the time it takes the object to cover the total distance.
Therefore the Average speed can be calculated with following formula:
[tex]Average\ speed=\frac{Total\ distance}{Elapsed\ time}[/tex]
Then, knowing the values of the Total distance and the Elapsed time, you can substitute those values into the formula and then evaluate.
