The speed of the ball is
ds/dt = 32t
At t =1/2 s
ds/dt = 16 ft/s
The distance from the ground
50 - 16(1/2)^2 = 46 ft
The triangles formed are similar
50/46 = (30 + x)/x
x = 345 ft
50 / (50 - s) = (30 + x)/x
Taking the derivative and substituing
ds/dt = 16
and
Solve for dx/dt
It would be 3:45 because 12:00 + 3:00= 3:00+0:45=3:45 and if u were to add another quarter (15mins) itd be 4:00
Your answer is C hope this helps
