Gerald hits his golf ball down the fairway. The path the ball followed was parabolic in shape with the relationship:

h=2d-1/30d^2

where h is the height above the ground of the golf ball when it is a horizontal distance d from him. Both h and d are in metres. How far from Gerald did the golf ball land?

it is at ground level when d = 0 and when

2 - d/30 = 0

or when d = 60
