Given that, Cassie is driving to the beach for vacation. The beach is 400 miles away. It takes her 8 hours to get there.
We need to find her average speed. We know that the total distance traveled by an object per unit time is called its average speed. It can be calculated as follows :
[tex]v=\dfrac{400\ \text{miles}}{8\ \text{hour}}\\\\v=50\ \text{miles per hour}[/tex]
So, her average speed is 50 miles per hour.
