Suppose velocity of an object is 5.7 miles per hour. When asking this as a question, say, what is velocity in m/s -- meaning meters/sec then we think dimensional analysis: 1 mile = 5280 ft, 1 ft = 12 in., 1 m = 39.37 in., 1 hour = 60 min, 1 min = 60 s In short ft to in to meters; also hours to min to seconds. -- dimensional analysis. However, in all this, do we think that avg velocity = change in distance/change in time. Please explain.
