Taking the point directly under the center of the bridge as the origin,
x = 20t, y = 15t, z = 10
let s be thedistance between them at time t,
s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100
2s ds/dt = 1250t
ds/dt = 625t/s
when t = 3, s = √(625*9+100) = 75.6637
ds/dt = 625*3/75.6637 = 24.78 m/s
18 : 24 = 18/24 = 3/4 <==
Answer: 625
Step-by-step explanation:
Do 5 to the third power, get the answer, and then multiply times 5 to get 625. Please mark this as the brainliest answer <3
