Answer:
Step-by-step explanation:
At time t seconds after the bike passed, the distance z between the balloon and the bike is
z^2 = (84+2t)^2 + (12t)^2
So, at t=6,
z^2 = (84+2*6)^2 + (12*6)^2 = 14400
So, z = 120
2z dz/dt = 2(84+2t)*2 + 2(12t)*12
At time t=6,
240 dz/dt = 2(84+2*6)*2 + 2(12*6)*12 = 2112
dz/dt = 2112/240 = 44/5 ft/s
