Two trucks are driving to the same place. The first truck starts 50 miles ahead of the second truck and travels at an average sp
eed of 60 miles per hour. The second truck travels at an average speed of 70 miles per hour. Which graph represents this situation and shows the number of hours it will take for the second truck to pass the first truck?
Well obviously the two bottom graphs don't represent the two trucks meeting. So we can cross those out. Looking at the top two graphs we can tell that the line above is truck #2. In graph 1 it shows the second truck is slowing down which is wrong since that isn't told.
