On the way to class, you walk north and then west such that your resultant displacement is 290 m in a direction 25deg west of north. Your average velocity is 2.0 m/s in the same direction as the displacement.
Calculate (a) your walking time and (b) your average speed.
Magnitude of displacement (vector)
Walking time = distance /speed
= 290m / 2.0m/s
= 385.4m / 145s
= 2.66 m/s
