Show your work and we will tell you where you made a mistake.
During the first 0.2 hours, the train moves 8 km. During the next 0.2 hours, the train moves 12 km. Now figure out how far it travels in the last 0.4 hr, add up the three distanceas and divided by the total elapsed time.
Average speed = (total distance traveled)/(elapsed time)_
