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
1,150ft + 35ft = 1,185ft
The reason you wouldnt subtract would be that you cant have negative 35 ft. You add the two heights together to produce your answer.

Answer:
Step-by-step explanation:
Let Ram's salary = ₹ x
Money donated to NGO = (2/3) of x
Money spent on food items = (1/5) of x
Other expenses = (1/5) of x
Balance amount = ₹ 9000
x = 9000 * 15
x = ₹ 135000
