Average velocity $\approx$ 2.7 m/s due east Average speed = 8.0 m/s
Let due east be the positive direction Time = 5 $\times$ 60 = 300 s Displacement = $x_{f}$ - $x_{0}$ = 800 - 0 = 800 Average velocity = $\frac{displacement}{time}$ = $\frac{800}{300}$ $\approx$ +2.7 m/s (2.7 m/s due east) Distance = 1600 + 800 = 2400 m Average speed = $\frac{distance}{time}$ = $\frac{2400}{300}$ = 8.0 m/s
