I have a data frame with 25000 rows containing two columns Time and Distance.
When I plot a simple distance versus time plot, the plot is very confusing
showing no general trend because of the large data. Is there any way I can
improve the plot by lets say using moving average as in EXCEL ? please also
suggest some other methods to make the graph smoother and better looking.

I recommend using the quantreg package to fit a quantile regression
model using a spline function of Time. Draw the estimated curves for
selected quantiles such as 0.1 0.25 0.5 0.75 0.9. A new function Rq in
the Design package makes this easier but you can do it with just quantreg.
