I assume you provided only the west longitude change data in degrees, decimal minutes.
I picked an arbitrary point
Point 1
43 deg 32.583 min N
-71 deg 15.319 min W
And then assumed westerly movement to:
Point 2
43 32.583
-71 15.321
And then more west to:
Point 3
43 32.583
-71 15.359
Using the coordinate transformation to get the UTM easterly:

The easterlies are:
Point 1: 317,798 meters
Point 2: 317,795 meters or 3 meters west of point 1
Point 3: 317,774 meters or 24 meters west of point 1
Again assuming no keyboard errors on my part and remembering that the conversion to UTM is rounded to nearest meter.
Of course the distance per minute of longitude is a function of how far north of the equator you are:
