1. The problem statement, all variables and given/known data A plane flies 2750 m[W] in 25s and then 5810m in 67s a) What is the average speed of the plane? b) What is the average velocity of the plane? I tried doing it and I don't know if I'm right. My physics teacher can't explain anything for beans so could you please explain the processes you go through while trying to achieve your answer. My teacher never gave me any formulas so..here's my attempt... Vav= Distance/time??? so 5810-2750/67-25?? Vav(velocity)= v1+v2/2 soo -2750+(-5810)/2??? 2. The problem statement, all variables and given/known data Determine the ground speed of a boat which can go at 25km/h, but is traveling [E] in a river that flows at 5km/h . I have no clue what this question is asking nor what to do!! pleaseeee help!
