Marcos did not travel at a constant speed on this drive. Which graph could represent how Marcos' distance traveled (in miles) and the number of hours since he left Phoenix change together? Select an answer b. Determine Marcos' average speed for the 155 mile trip. miles per hour c. Devon also drove to Flagstaff, leaving at the same time and from the same location as Marcos, and arrives in Flagstaff at the same time. Devon has cruise control and travels at a constant speed for the entire trip. i.
