How do I extrapolate a point from a generated graph.

So this is the question

The velocity (ms-1) of a car is measured every minute for 24 minutes and recorded as:

vel = [0 .45 1.79 4.02 7.15 11.18 16.09 21.90 29.05 29.05

29.05 29.05 29.05 22.42 17.9 17.9 17.9 17.9 14.34 11.01 8.9

6.54 2.03 0.55 0];

How long did the object take to pass 250m?

I have successfully generated a time against cummulative distance graph, but I'm stuck now.

Many thanks

The easiest way is to use the interp1 (link) function to get the time when the car has travelled 250m.
