A quarterback throws a football toward a receiver

A quarterback throws a football toward a receiver with an initial speed of 20 m/s at an angle of 30° above the horizontal. At that instant the receiver is 20 m from the quarterback. In (a) what direction and (b) with what constant speed should the receiver run in order to catch the football at the level at which it was thrown?

For people trying to understand this question
"Drew Brees of the New Orleans Saints can throw a football 23.0 m/s (50 mph). If he angles the throw at 10°
from the horizontal, what distance does it go if it is to be caught at the same elevation as it was thrown?"

Thank you very much :S Its just been quadratics but wasn't sure what to do when my c value is 0 and this helped me figure it within .2 range of answer - thank you thank you <3

This helped me and I thank you for that! But how come you use the same variables like with the distant one and the Vox?
