Suppose the tern travels 16513 km south, only to encounter bad weather. Instead of trying to fly around the storm, the tern turns around and travels 617 km north to wait out the storm. It then turns around again immediately and flies 14814 km south to Antarctica. What is the tern's average speed in km/h if it makes this trip in 144 days? (Please round your answer to two decimal place; DO NOT include units)It's showing that b is not correct. Thank you for your help with this practice problem.
