1011.2: Fallcoming Transportation Solution

 

Congratulations to Tom Williams '11 for winning the second logic puzzle contest. Tom's name was picked at random from among the other correct entries submitted by: Amelia Mattern '12; Sam McNerney '11; Sunrose Shrestha '14; Evan van Tassell '13; Ian Thresher '12; and Walter Zonenberg '14. Thanks to everyone who submitted solutions!

 

In our last puzzle, you were asked to determine how to transport three students and three alumni, using a two-seat golf cart, from the Chapel to the Sadove Student Center. All three students, but only one of the alumni, could drive the cart. At all times, there had to be at least as many students as alumni at both the Chapel and the Sadove Student Center, whenever there was at least one of each.

 

Let's call the students 'S', the driving alumnus 'A', and the other alumni 'a'.
