 Which has a greater velocity? A ball rolling down a 3.4m hill in 8.5s or a fish swimming upstream, covering 6.2m in 0.6 minutes?  (velocity = change in distance / change in time)

Question 6 options:

They have the same velocity

the fish

the ball

they can't compare because they have different time units

Ball speed  = 3.4m / 8.5s  = 0.4 m/ s

 

Fish speed  = 6.2m / 0.6 min  =  6.2m / 36 s =  0.172 m/s

 

The ball
