Mechanics 1 - Vectors

Hi can someone please help with a Vectors question?

On another occasion, John has position vector 40j m. He wishes to skate in a straight line to the point with position vector 30i m. Given that his speed is constant at 5m/s, find his velocity

Is your issue understanding what the question is asking?
If not, have you attempted the question?

Are you happy with how to use direction and velocity as vectors? (In terms of i and j)

I think so yes

You need to find a unit vector in his direction of travel and then mutiply it by 5 - velocity has magnitude and direction.
