Error/plotting inside a loop

Greetings everyone, so I have the following simple code with a for loop in which I want to calculate the distance a car has travelled every 10 minutes. I would like to plot each “spot” it is calculated in the for loop and add it in the diagram. But for some reason I get the error “Cannot convert Float64 to series data for plotting” in the 12th line! What could I do to overcome this problem?

using Plots
function f()
    v = 119 #km/hour
    D = 0.0 #distance
    t_tot = 2.0 #total hours
    dt = 1/6 #10 minute interval
    nt = t_tot/dt; #number of iterations
    t = 0.0
    for i in 1:nt
        t = t .+dt
        D = D .+v*dt 
        p = scatter!(t,D)
    display(p)
    sleep(0.3)
    end
end
f()

You probably need to do scatter!([t], [D])

And to save 2 brackets: scatter!((t,D))

Ah yes it worked!! The solution was much simpler than I expected ahahha. Thank you so much!
