you have been given the horizontal and vertical components of velocity, can you see how drawing a triangle might help you?

Well, the horizontal and vertical components of velocity are at right angles to each other, so to find the speed, you can use pythagoras on them. (hor vel)^2 + (vert vel)^2 = (speed)^2 This should give you a quadratic equation for speed in terms of t which you can find the minimum of.
