Campus Shuttle Detour Announcement
You hear a campus shuttle driver make an announcement. 'Attention passengers: because of construction on College Avenue, the Blue Route will not stop at the museum or at the athletic center today. We will stop at the library, then go directly to the north parking lot. The detour adds about eight minutes. If you need the athletic center, get off at the library and take the Red Route; it leaves from the library every 15 minutes. The museum is closed today anyway. The next stop is the library.'
1. Which two stops will the Blue Route skip today, and why?
Read the worked answer
The museum and the athletic center. The driver says construction on College Avenue means the Blue Route will not stop at either one. The museum is also closed today, but the stated reason for the route change is construction. The Blue Route will instead stop at the library and then go to the north parking lot.
2. A passenger wants the athletic center. What does the driver say the passenger should do, and what wait should the passenger expect?
Read the worked answer
The passenger should get off at the library and take the Red Route. The Red Route leaves the library every 15 minutes, so the passenger may wait up to 15 minutes. The announcement does not give the Red Route travel time, so the total trip cannot be calculated from this message. The direct Blue Route stop is not available today.
3. What does the announcement imply about why the museum is not a stop?
Read the worked answer
The main reason is the construction detour, because the driver lists the museum with the athletic center as a skipped stop. The driver adds that the museum is closed today anyway. This implies that even without the detour, a museum stop might not be useful today, but the route change itself is caused by construction.
