Li went for a mountain-bike ride in a relatively flat wooded area. She rode for 6 km in one direction and then turned and pedaled 16 km in another. Finally she turned in the direction of her starting point and rode 8 km. When she stopped, was it possible that Li was back at her starting point? Explain.
Think of these as negative and positive numbers starting at the starting-point, which is 0. 0+6-16+8 = -2 It doesn't go back to 0, so no, it isn't possible that Li was back at her starting point. Hope this helps <3
