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"" ")|)
