Use the following information to answer question 26-28.

Two trains travel the same route from Toronto to Montreal, a distance of 550 km. The Local leaves Toronto earlier than the Express, makes 3 stops at stations along the way, and arrives in Montreal later than the Express. Assume that the Local travels at a constant speed on each of the 4 parts of the route, but not necessarily at the same speed for all 4 parts, and that the Express travels at a constant speed. The schedule for the Local and a graph for the Local and the Express are shown below.
