Jordan walks 250 m North towards school. He forgets his backpack and walks 250 m South back to his house. He then finds his backpack and walks 900 m North. He gets to school in 9 minutes. What is his velocity in meters per minute

10 m / minute

Step-by-step explanation:

Starting position = North ; back to North gives a Displacement of 0 ; the from that position to 900 m south gives a final Displacement of 900

Displacement / time

Displacement = 900

Time = 9 minutes

900 / 9

= 10 m / minute
