Well, why not just sketch a grid and do what each of the rats do ?
I am sure you can follow the steps just as well as any of us.
I suggest you make the origin your starting point.
It easy to see that Riley ends up at (7,3) with the cake at (7,4)
Do the same for the other rat
Three scientists are observing Rickey and Riley, laboratory rats, to see how long each rat takes to find a piece of cake in a maze. The maze is a large box with open pathways running north-south and east-west in a grid pattern. Riley takes the direct route by traveling three rows north, turning right and traveling two columns east, proceeding four rows north and turning right for one column. He is one row south of the cake when the bell goes off. Rickey, on the other hand, fumbles his way along. He enters at the same gate as Riley and advances twelve rows north. He then becomes confused and does an about-face, and moves eight rows south along the same path. Then he moves left one column and north one row. Finally he makes a right turn and moves four columns to the east. How far away from the cake is Rickey if the bell goes off at this point?
