Irvin recorded both his location and velocity while he rode his motorcycle; however, he forgot to label the data and thus mixed up the distance and velocity measurements. Hoping to straighten out the data, he created two graphs. Which graph below represents distance and which graph represents velocity? How do you know? 

Graph A
Upward increasing curve, coming from, point on negative x axis, turning at point on positive y axis, decreasing & staying upward, to a point on positive x axis.

Graph B
Increasing curve, coming from left above x axis, changing from opening up to opening down at a point on the y axis, then continuing right with slight increase in y.

Think back to the Freeway Fatalities problem: 1-1. Recall that velocity is the slope of a distance/position graph, while distance is the area under a velocity graph.
