Explanation:
The equation of the average speed os given by:
(1)
here:
Δx is just 195 miles
Δt is the time traveled. 3.25 h ( 3 h + 15 min or 0.25 h)
So we just need to put this into the equation (1)
Therefore, the average speed is
![v=60 miles/h](https://img.qammunity.org/2021/formulas/mathematics/high-school/k32vvqys3uid3re0s5ifwcytko0cdobxbx.png)
I hope it helps you!
