Answer:
38.5 pages
Step-by-step explanation:
11pages:2mins
x pages: 7 mins
you need to divide 7 by 2 and get 3.5, then multiply 3.5 by 11 and receive 38.5
If you have pick it, then you should be offered choices and you should include them in the question.
The answer is 3.09

Answer:
1 m/s
Step-by-step explanation:
the area of the triangle = A = ¹/₂ab
where a is the distance covered by the first person and b is the distance covered by the second person. since they walk at the same speed, then a = b, so our formula can be changed to A = ¹/₂x²
now we find the derivative of both sides:
dA/dt = ¹/₂ ⋅ dx²/dt
dA/dt = ¹/₂ ⋅ 2x ⋅ dx/dt
dA/dt = x ⋅ dx/dt = x ⋅ velocity
we are told that x = 5 m, and dA/dt = 5 m²/s
velocity = dA/dt / x
velocity = 5 m²/s / 5 m = 1 m/s
