Felipe is moving towards Lilah at velocity
[tex]v_f = +15 km/h[/tex]
and the velocity of the football with respect to Felipe is
[tex]v_b=+8 km/h[/tex]
Therefore, the velocity of the football relative to Lilah is the sum of the two velocities:
[tex]v=v_f+v_b=15 km/h+8km/h = 23 km/h[/tex]

Answer:

23 km/h
