## Main Question or Discussion Point

Hi,

I have a set of experimental data given in terms of speed [itex]u[/itex] versus distance [itex]x[/itex]. But I want to obtain a plot of distance [itex]x[/itex] versus time [itex]t[/itex]. The problem is I don't have the end time of the experiment. In this experiment velocity is a function of distance, [itex]u=u(x)[/itex] and distance is in turn of time, [itex]x=x(t)[/itex].

[itex] \frac{dx(t)}{dt} = u(x)[/itex]

Is this possible without knowing the start and times?
