bird flies 3.50 km [East] and then immediately turns around and flies 7.50 km [West]. The bird's average speed for the entire motion is 11.0 km/h. What is the bird's average velocity. Give your answer in km/h to 2 decimal places. A velocity that is west should be treated as negative and a negative sign should be included in your answer. A velocity that is east should be treated as positive but no sign should be included in the answer. Do not include units in your answer
