1. The problem statement, all variables and given/known data An airplane flying North at 119.7 m/s encounters a 46.8 m/s tailwind. If the plane's destination is 573 km due North, what will its travel time be? 2. Relevant equations 3. The attempt at a solution I added the two velocities: 166.5 m/s. Then divided that by 573000, but that's not right becasue I get a very small number of seconds. What I am doing wrong.
