Bus Scheduling is a puzzle in Professor Layton and the Unwound Future.

## Puzzle

US Version

It takes you one hour to get to the office by bus. Your work takes two hours to complete, after which you catch the bus home.

Based on the departure times listed below, which bus, A,B,C,D, or E, should you take to work in order to minimize the wait for a ride home?

Note: The departure times for the buses home are listed to the right.

UK Version

Your bus journey to work takes one hour. You work for two hours, then take the bus home from the bus stop next to where you work. The bus timetables to and from work are shown below.

You want to make the time between getting on the bus to work and getting off the bus from work as short as possible. Which bus should you take to work in order to achieve this?

Touch the letter next to the departure time of this bus.

It doesn't matter what time you get to work, so you can take any of the buses and be fine. But once you get there, you're stuck taking whatever bus leaves the soonest after you finished working.

For example, suppose there was a bus you could take to the office at 12:30pm. In this case, you would arrive at 1:30pm. It takes two hours to finish your work, so by the time you were done, it would be 3:30pm. That's the soonest you could catch a bus home.

So for each of the buses going to the office, figure out what time you'd be done working and ready for a ride home.

You're not overlooking any choices because they seem to late, are you?

As long as you get your work done, you can show up at whatever time works best for you.

Go to work late, head home first thing in the morning: this schedule is the most time effective, so which bus is it?

## Solution

### Incorrect

Maybe making some notes on the bus timetable will help you work it out.

### Correct

US Version

Righty-o!

Taking bus E to work at midnight will result in the shortest wait for a ride home. Your bus will leave home at 5:00am.

UK Version

That's right!

Taking the midnight bus to work and catching the first bus back in the morning will take the least amount of time overall.
