Answer:
12s.
Step-by-step explanation:
Given:
Hudson's velocity, Vh = 8.8 ft/s
Katie's velocity, Vk = 6.3 ft/s
Kate's head start distance, Dk = 30 ft
From the above, Katie and Hudson meet at th = tk = t
But, Dk = Dh + 30
Velocity = Distance/time
t × Vk = Dk
t × Vh = Dh
t × Vk + 30 = Dk
t × Vk + 30 = Vh × t
6.3t + 30 = 8.8t
t = 30/2.5
= 12 s
6* 25 = 150 = (6*20= 120) + (6*5=30) Then Add 120+30= 150 so your answer is 5
