Answer:
you get the answer yet im trying to figure it out to
Step-by-step explanation:
Answer:
The average speed is:
![\var{v}=75\: miles/h](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D75%5C%3A%20miles%2Fh)
Step-by-step explanation:
The average speed equation is given by:
![\var{v}=\frac{\Delta x}{\Delta t}](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D%5Cfrac%7B%5CDelta%20x%7D%7B%5CDelta%20t%7D)
Were:
- Δx is the displacement (225 miles)
- Δt is the change in time (3 hours)
Then we have:
![\var{v}=\frac{225}{3}](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D%5Cfrac%7B225%7D%7B3%7D)
![\var{v}=75\: miles/h](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D75%5C%3A%20miles%2Fh)
I hope it helps you!
