Question

7. What is the velocity (in km/h) of Mr. Schaller when he ran 4.5km [South] to WH Croxford School in 0.75 hours? (3 marks)

Answer 1

Answer #1

Distance travelled, $x=4.5\, km$

Time, $t=0.75\, hours$

So, velocity,

$v=\frac{x}{t}=\frac{4.5}{0.75}=\mathbf{6\, km/h}$

Direction of velocity is also in southern direction.
