Question

A plane's average speed between 2 cities is 800 km/hr. If the trip takes 4.5 hours howfar does the plane fly?

Answer 1

Considering the average velocity can be written as:

`v=(\Delta s)/(\Delta t)`

We can isolate the distance, and we get:

`\Delta s=v*\Delta t\rightarrow\Delta s=800*4.5=3600km`

Then, the distance the plane flew is 3600km
