Harry walks 1.5 km/h to the mall. Earl walks 2.75 km/h to the mall. What is Earl's relative velocity with respect to Harry?
v = sqr(2.75^2-1.5^2)
To find Earl's relative velocity with respect to Harry, we need to subtract Harry's velocity from Earl's velocity.
Earl's velocity = 2.75 km/h
Harry's velocity = 1.5 km/h
Now, subtract Harry's velocity from Earl's velocity:
2.75 km/h - 1.5 km/h = 1.25 km/h
Therefore, Earl's relative velocity with respect to Harry is 1.25 km/h. This means Earl is moving 1.25 km/h faster than Harry towards the mall.
