v_("av-"x) = 42.7 "m/s"

Explanation:

We're asked to find the (average) velocity of the car, given the distance it traveled and the time interval.

The equation for one-dimensional average velocity here is

v_("av-"x) = (Deltax)/(Deltat)

where

  • Deltax is the displacement

  • Deltat is the time interval

We know:

  • Deltax = 2560 "m"

  • Deltat = 60 "s"

So the average velocity is

color(red)(v_("av-"x)) = (2560color(white)(l)"m")/(60color(white)(l)"s") = color(red)(ulbar(|stackrel(" ")(" "42.7color(white)(l)"m/s"" ")|)
