    A bicyclist pedals along a straight road with velocity, v, given in the figure below. She starts 3 miles from a lake; positive velocities take her away from the lake and negative velocities take her toward the lake. http://i.imgur.com/lhJQd.png Approximately how far away is she at this time? Give a best estimate.

    just count the number of squares

    Please define "under". That first 20 is troublesome.

    It includes both the negative and positive velocities, so not exactly under for both

    0 is the x axis of course

    They basically want you to count squares here.

    That seems too simple. What would be the units I would use?

    The count the number of square when it is above, and subtract from the the number of square when it is below.

    The square is 10mph time is 1 h So the result is 10 miles for each square

    Keep it simple, they asked for an approximation.

    What should I do for the squares that aren't whole?

    It seems a bit tricky go guess

    if you want to make it more complicated, then just roughly estimate how much of a square it is.

    Okay, I will try my best to approximate it. Thank you
