Rock is on ground when height y = 0, so we need to solve 
y = -0.02x^2 + 0.8x + 37 = 0, to find options for horizontal distance x. 
this equation may seem more normal if we multiply throuhh by -50. 
x^2 - 40x - 1850 = 0 with positive solution selected as 
x = 20 + 15√(10) ~ 67.43 metres 
i hope this you : )
