Lisa and Craig traveled during the holidays to visit their family. The distance and driving time are shown in the graph below. Which conclusion can be made from the graph?

• They stopped often along the way

• They traveled at a fairly constant velocity

• There were different drivers at different times

• They were driving slowly at first and then increased their velocity every hour
