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"" ")|)#
