Rachel the robot is exploring an alien planet. Her computer brain keeps track of the world around her in terms of x and y coordinates (see graph below). Rachel is running low on battery. She wants to collect a rock sample before returning to her charging station, but she is worried this may cause her to run out of battery. How much shorter would it be for Rachel to go straight to her charging station than for her to collect the rock along the way?
