Review. The biggest stuffed animal in the world is a snake 420 m long constructed by Norwegian children. Suppose the snake is laid out in a park as shown in Figure P3.53 forming two straight sides of a 105° angle with one side 240 m long. Olaf and Inge run a race they invent. Inge runs directly from the tail of the snake to its head and Olaf starts from the same place at the same moment but runs along the snake. (a) If both children run steadily at 12.0 km/h Inge reaches the head of the snake how much earlier than Olaf? (b) If Inge runs the race again at a constant speed of 12.0 km/h at what constant speed must Olaf run to reach the end of the snake at the same time as Inge?
