You have exactly 5 minutes 13 seconds to get to your next class on time and that classroom is 418 m east of where you are right now. First you run to your dorm room at an average velocity of 4.92 m/s to the south to pick up your calculator and your dorm room is 477 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time?  2.03 m/s  4.92 m/s  2.94 m/s  2.86 m/s
